How to Connect a Handheld Gaming PC to an External eGPU?

Your handheld gaming PC is great on the go. But what if you could turn it into a desktop powerhouse the moment you get home? That is exactly what an external GPU (eGPU) lets you do. Instead of buying a full desktop computer, you can plug a dedicated graphics card into your handheld and play AAA games at higher settings on a big screen.

The concept is simple. Your handheld has a capable processor but limited graphics performance. An eGPU adds a full desktop or laptop class graphics card through a high speed cable. The result? Up to four times the GPU performance compared to what your handheld can produce on its own.

But getting this setup running is not always plug and play. You need to choose the right connection type, pick a compatible enclosure, install proper drivers, and troubleshoot issues that pop up along the way. Many gamers have tried and failed because they missed one or two critical steps.

This guide walks you through the entire process. From understanding connection types like Thunderbolt and OCuLink to solving common problems like Error 43, you will find everything you need to get your eGPU working with your handheld gaming PC.

Key Takeaways

• An eGPU can boost your handheld’s graphics performance by 3x to 4x, turning a portable device into a capable desktop replacement for gaming and creative work. Real world tests show that a handheld paired with an AMD Radeon RX 7600M XT can quadruple its 3DMark Time Spy Extreme graphics score.
• Thunderbolt 4 and OCuLink are the two main connection standards for eGPU setups. Thunderbolt offers hot swap convenience and wide compatibility. OCuLink provides higher bandwidth (up to 64 Gbps vs 40 Gbps) and lower latency at a lower price. Thunderbolt 5 doubles bandwidth to 80 Gbps and narrows the gap with OCuLink significantly.
• You will need three core components: a compatible handheld with the right port, an eGPU enclosure with a sufficient power supply, and a dedicated graphics card. Budget at least a few hundred dollars for the enclosure alone.
• Driver installation is the most critical software step. You must use DDU (Display Driver Uninstaller) to remove old drivers before installing the new GPU driver. Mismatched or conflicting drivers cause most eGPU failures on handheld PCs.
• An external monitor is strongly recommended. Routing the eGPU output back to the handheld’s internal display can cause frame loss and instability. A direct display connection from the eGPU delivers the best experience.
• CPU bottlenecks are real. Handheld processors are low power chips. Pairing a high end GPU like an RTX 4090 with a 15W to 28W handheld CPU will leave much of the GPU performance unused. A mid range card like an RTX 4060 or RX 7600 often delivers the best value.

What Is an eGPU and Why Does It Matter for Handhelds

An eGPU is a dedicated graphics card that sits outside your computer. It connects through a high speed cable and handles all the heavy graphical processing your handheld cannot do on its own. Think of it as a graphics upgrade that you can plug in and unplug whenever you want.

Handheld gaming PCs like the ROG Ally, Lenovo Legion Go, and Steam Deck use low power APUs. These chips balance CPU and GPU on a single piece of silicon. They run at 15W to 28W, which keeps battery life reasonable but limits graphics performance. Most handhelds can play modern AAA games only at medium or low settings with reduced resolution.

An eGPU removes this limitation. By offloading the graphics processing to a dedicated card inside an external enclosure, your handheld can drive games at 1080p, 1440p, or even 4K with high or ultra settings. In real world testing, a One XPlayer Mini Pro paired with a Radeon RX 7600M XT doubled the frame rate in Tekken 8, jumping from 31 FPS to a steady 60 FPS.

The setup also has benefits beyond gaming. Productivity tasks like video editing, 3D rendering, and AI powered photo editing see massive improvements. Adobe Lightroom’s AI Denoise, for example, ran nearly ten times faster with an eGPU compared to using the integrated GPU alone.

Pros: Massive performance boost, flexible setup, works for both gaming and productivity, keeps the handheld portable when disconnected.

Cons: Adds cost (hundreds of dollars for enclosure plus GPU), requires compatible ports, introduces some bandwidth overhead, and you lose mobility while connected.

Understanding Connection Types: Thunderbolt vs OCuLink vs USB4

The connection between your handheld and the eGPU determines how much performance you actually get. Not all connections are equal. Bandwidth is the key factor, and the three main standards offer very different amounts of it.

Thunderbolt 3 and 4 both provide 40 Gbps of bandwidth through a USB C connector. This translates to PCIe 3.0 x4 speeds. The technology is mature and widely supported. You can hot swap (plug and unplug without restarting), and many eGPU enclosures are built for Thunderbolt. However, the 40 Gbps limit means you lose roughly 10% to 20% of the GPU’s potential compared to a direct PCIe slot.

Thunderbolt 5 is the newest standard, offering 80 Gbps bidirectional bandwidth. This effectively doubles the available data pipeline. Early testing shows it reduces the performance gap between eGPU and desktop setups significantly. The Razer Core X V2 is one of the first consumer enclosures to use Thunderbolt 5.

OCuLink (Optical Copper Link) provides a direct PCIe connection with up to 64 Gbps bandwidth at PCIe 4.0 x4 speeds. It does not packetize data the way Thunderbolt does, which means lower latency. The downside is that OCuLink does not support hot swapping, and fewer devices include this port.

USB4 is functionally similar to Thunderbolt 4 for eGPU purposes, offering 40 Gbps. Some newer handhelds use USB4 ports that are compatible with Thunderbolt eGPU enclosures.

Pros of Thunderbolt: Hot swap support, wide compatibility, plug and play convenience. Cons of Thunderbolt: Lower bandwidth than OCuLink, data packetization adds overhead.

Pros of OCuLink: Higher bandwidth, lower latency, lower cost enclosures. Cons of OCuLink: No hot swap, limited device support, fewer enclosure options.

Checking Your Handheld’s Compatibility

Before you buy anything, you need to verify that your handheld gaming PC actually supports an eGPU connection. Not every handheld has the right port or firmware to make this work.

Start by checking which ports your device has. The ROG Ally and Ally X feature a USB4/Thunderbolt compatible USB C port. The Lenovo Legion Go uses USB4. Some devices from One XPlayer and AYANEO include dedicated OCuLink ports or proprietary connectors. The Steam Deck, however, does not natively support eGPU connections through its USB C port without significant workarounds.

Next, look at the specific USB C port specifications in your device’s documentation. A USB C port that only supports USB 3.2 will not work with a Thunderbolt eGPU enclosure. You need a port that explicitly supports Thunderbolt 3, Thunderbolt 4, Thunderbolt 5, or USB4 with PCIe tunneling.

Check your device’s BIOS or firmware as well. Some handhelds require a BIOS update or a specific setting to enable external GPU support. The Lenovo Legion Go, for example, may need specific driver versions from Lenovo’s website to properly recognize an eGPU.

Also verify the power delivery requirements. Many eGPU enclosures can charge your handheld through the same cable. If your handheld draws up to 65W and the enclosure provides 100W power delivery, you can game while charging. This is a significant convenience factor.

A quick compatibility checklist: Confirm Thunderbolt or OCuLink port availability, verify the port version and bandwidth, check BIOS/firmware for eGPU enable options, and confirm power delivery specs.

Choosing the Right eGPU Enclosure

The eGPU enclosure holds your graphics card, provides power, and connects to your handheld. Choosing the right one matters because it affects compatibility, performance, and overall experience.

Full size enclosures accept standard desktop GPUs. They typically include a built in power supply rated at 500W to 750W, which is enough for most graphics cards. These enclosures connect through Thunderbolt and support a wide range of GPUs from both NVIDIA and AMD. They are larger and heavier but offer the most flexibility in GPU choice.

Compact or portable eGPU docks come with a built in laptop GPU. Products like the OneXGPU and the ASUS ROG XG Mobile include an embedded graphics card, so you do not need to buy a separate GPU. The 2025 ROG XG Mobile uses Thunderbolt 5 and includes modern laptop GPUs with GDDR7 memory. These are more portable but offer less upgradeability.

DIY eGPU adapters are the most affordable option. A simple PCIe to Thunderbolt or OCuLink adapter board paired with an external ATX power supply and an open air GPU mount costs far less than a retail enclosure. The tradeoff is no case protection, exposed components, and a messier setup.

When choosing an enclosure, consider these factors: Does it fit the GPU you want to use (check length and slot size)? Does it provide enough power (at least 150W above the GPU’s TDP is a safe margin)? Does it match your connection type (Thunderbolt or OCuLink)? Does it offer additional features like USB ports, Ethernet, or display outputs?

Pros of full size enclosures: GPU flexibility, future upgradeable, stronger power supplies. Cons: Expensive, bulky, not portable.

Pros of compact eGPU docks: Portable, all in one solution, clean setup. Cons: No GPU upgrade path, often proprietary.

Selecting the Best GPU for Your Handheld

Pairing the right GPU with your handheld is critical. A common mistake is buying the most powerful card available without considering the CPU bottleneck that handheld processors create.

Handheld APUs run at 15W to 28W. These processors can only feed so much data to the GPU before they become the limiting factor. In practical terms, a mid range GPU will deliver almost the same gaming experience as a high end GPU because the CPU cannot keep up with the faster card.

For most handheld eGPU setups, an NVIDIA RTX 4060 or AMD Radeon RX 7600 offers the best performance per dollar. These cards are powerful enough to play AAA games at 1080p or 1440p with high settings, but they do not overwhelm the handheld’s CPU. Their power draw is also manageable, typically under 150W, which keeps the enclosure’s power supply requirements reasonable.

Going higher to an RTX 4070 or RX 7700 XT makes sense if you plan to game at 1440p or 4K and your handheld has one of the stronger APUs (like the AMD Ryzen Z1 Extreme at 28W). Beyond that, cards like the RTX 4080 or RTX 4090 will show diminishing returns because the CPU bottleneck grows larger.

Also consider the GPU brand relative to your handheld’s APU. Handhelds with AMD APUs (like the ROG Ally or Legion Go) can sometimes experience driver conflicts with AMD eGPUs. Some users report that NVIDIA cards are more straightforward to set up on AMD APU handhelds because the drivers are completely separate and do not conflict.

Pros of mid range GPUs: Best value, minimal CPU bottleneck, lower power requirements. Cons: Cannot push ultra settings at 4K.

Pros of high end GPUs: Maximum raw performance, better at higher resolutions. Cons: CPU bottlenecked on handhelds, higher cost, more power hungry.

Step by Step Hardware Setup

Getting your hardware connected is the first physical step. Follow this sequence to avoid damaging components or running into connection issues.

Step 1: Power off your handheld completely. Even if your connection type supports hot swapping, doing the first connection with the device off is safer. This gives Windows a clean chance to detect the new hardware on the next boot.

Step 2: Install the GPU into the enclosure. Open the enclosure, remove any protective covers from the PCIe slot, and seat the graphics card firmly. Secure it with the included screws. Connect any required PCIe power cables from the enclosure’s power supply to the GPU. Make sure all connections are tight.

Step 3: Connect the cable. Plug the Thunderbolt or OCuLink cable into the enclosure. Then connect the other end to your handheld. For Thunderbolt, use the cable that came with the enclosure. For OCuLink, make sure you have the correct SFF 8611 connector type.

Step 4: Connect your external monitor. Plug an HDMI or DisplayPort cable from the eGPU’s graphics card directly to your monitor. This is the recommended output method. Routing the display signal back through the handheld’s internal screen adds latency and often causes instability.

Step 5: Power on the enclosure first. Turn on the eGPU enclosure and wait a few seconds for it to initialize. Then power on your handheld. Windows should detect the new GPU during boot.

Step 6: Verify detection. Open Device Manager on Windows. Look under Display Adapters. You should see both the integrated GPU and the external GPU listed. If the external GPU shows a yellow warning triangle, you need to address the driver situation (covered in the next section).

Installing Drivers the Right Way

Driver installation is where most eGPU setups fail. Handheld PCs already have integrated GPU drivers installed. Adding a second GPU, especially from a different vendor, requires careful driver management.

Start with a clean slate. Download DDU (Display Driver Uninstaller) from a trusted source. Boot your handheld into Safe Mode. Run DDU and select the option to remove all GPU drivers and restart. This removes every trace of the old GPU driver, which prevents conflicts with the new eGPU driver.

After restarting, do not let Windows automatically install drivers. Windows Update often installs generic or outdated drivers. Go to Settings, then Windows Update, then Advanced Options. Turn off the option that says “Receive updates for other Microsoft products.” This gives you time to install the correct drivers manually.

Now install the drivers in the right order. First, go to your handheld manufacturer’s website (Lenovo, ASUS, etc.) and download the latest chipset driver for your device. Install it and restart. Next, download the latest GPU driver from NVIDIA or AMD for your specific external GPU model. Install it and restart again.

One experienced user on the Lenovo Legion Go forums shared a successful process: DDU the old drivers, run AMD Cleanup Utility, install the OEM chipset driver from Lenovo, update Windows fully, then install the eGPU driver matching the same release date as the integrated driver. Driver version matching can be important for AMD to AMD setups.

After installation, open Device Manager again. Both GPUs should appear without yellow warning icons. If you see Error Code 43, this usually means a driver conflict or bandwidth issue that requires further troubleshooting.

Configuring Windows and Game Settings

After the drivers are working, you need to configure Windows and your games to actually use the external GPU instead of the integrated one.

Set the default GPU in Windows. Go to Settings, then System, then Display, then Graphics. Here you can assign specific applications to use the high performance GPU (your eGPU). Click on each game or application, select Options, and choose the external GPU from the list. This forces Windows to route those programs to the dedicated card.

For NVIDIA cards, open the NVIDIA Control Panel. Go to Manage 3D Settings, then the Program Settings tab. Select your game from the dropdown. Under “preferred graphics processor,” select your external GPU. This is an extra layer of control that ensures NVIDIA titles use the right card.

For AMD cards, open AMD Software: Adrenalin Edition. Navigate to the Gaming tab, find your game, and set the GPU preference to the external card. AMD’s software also lets you create per game performance profiles.

Resolution and refresh rate matter a lot. If you are outputting to an external monitor, set the resolution in Windows Display Settings to match your monitor’s native resolution. Also make sure the refresh rate is set to the highest value your monitor supports. A common mistake is gaming at 60Hz on a 144Hz monitor because the setting was not changed.

Inside each game, go to the graphics or video settings. Select the external GPU if the game offers a GPU selection option. Set the rendering resolution, quality preset, and frame rate target. Remember that your handheld’s CPU is still the processor, so avoid maxing out CPU heavy settings like draw distance and NPC density even if your GPU can handle it.

Using the eGPU With the Handheld’s Internal Screen

Some gamers want to use the eGPU’s power without plugging in a separate monitor. This is possible but comes with important caveats.

When you use an external GPU with the handheld’s built in screen, the rendered frames must travel from the eGPU, back through the cable, and to the handheld’s display controller. This round trip adds latency and consumes bandwidth in both directions. The result is lower frame rates compared to outputting directly from the eGPU to an external monitor.

Multiple users on community forums have reported that running an eGPU on the internal display is “unreliable and mostly unplayable” with certain configurations, especially AMD to AMD setups. The integrated GPU acts as a passthrough for the display signal, and this can cause frame pacing issues, stuttering, and even crashes.

That said, some setups do work reasonably well. Thunderbolt 5 improves the situation because its higher bandwidth reduces the bottleneck on the return path. Users with NVIDIA eGPUs on AMD APU handhelds also report better results because Optimus technology handles the display routing more gracefully.

If you want to try it, set Windows to use the eGPU as the primary display adapter. Go to Display Settings and configure the handheld screen as the only active display. Make sure the eGPU is selected in your game’s settings as the active renderer.

Pros of using the internal screen: No extra monitor needed, keeps the setup portable, good for couch gaming. Cons: Reduced performance due to round trip bandwidth usage, potential stuttering, incompatibility with some configurations.

The best practice for maximum performance remains a direct connection from the eGPU to an external display. Reserve the internal screen approach for casual or less demanding games.

Troubleshooting Common eGPU Problems

Even with a careful setup, things can go wrong. Here are the most common issues and their solutions.

Error Code 43 in Device Manager is the most frequent problem. This code means Windows recognizes the GPU but cannot use it. The fix usually involves running DDU in Safe Mode, removing all existing GPU drivers, and reinstalling fresh drivers. For NVIDIA cards, also try disabling the “NVIDIA Notebook GPU Checks” through a registry edit or a community tool specifically built for eGPU setups.

The eGPU disconnects randomly during use. This often happens with Thunderbolt connections if the cable is moved or not fully seated. Use a short, high quality Thunderbolt cable. Avoid bending or stressing the cable during use. If disconnections persist, check the Thunderbolt firmware on your handheld and update it through the manufacturer’s support page.

Games run at the same speed with or without the eGPU. This means the game is still using the integrated GPU. Verify GPU assignment in Windows Graphics Settings and in the NVIDIA or AMD control panel. Also check the game’s own settings for a GPU selection option.

The eGPU is detected but no display output works. Try a different output port on the GPU (DisplayPort instead of HDMI, or vice versa). Some GPU and monitor combinations have compatibility issues on specific ports. Also confirm that your monitor is set to the correct input source.

Blue screen or system crash on eGPU connection. This usually points to a driver conflict. An AMD APU paired with an AMD eGPU can clash if both use the same Adrenalin software version. The solution is to use the manufacturer’s OEM driver for the integrated GPU and the standard AMD driver for the eGPU, making sure their versions do not conflict.

Performance Expectations and Real World Benchmarks

Understanding realistic performance gains helps you set proper expectations and avoid disappointment.

In synthetic benchmarks, a handheld with an AMD Ryzen 7 6800U paired with a Radeon RX 7600M XT eGPU scored 4,484 in 3DMark Time Spy Extreme, compared to 1,258 without the eGPU. That is roughly a 3.5x improvement in overall score and a 4x improvement in pure GPU score. These numbers show the dramatic impact of adding a dedicated graphics card.

Real game performance varies by title. Tekken 8 jumped from 31 FPS to 60 FPS at high settings and 1920×1200 resolution. Risk of Rain 2 went from 62 FPS to 130 FPS. Elden Ring with ray tracing on medium improved from 23 FPS to 33 FPS, though ray tracing is generally less efficient on AMD hardware. Rocket League at max settings gained about 10 FPS on the handheld screen but showed a larger 42 to 73 FPS gain on a laptop with a higher resolution display.

Productivity workloads benefit enormously. DaVinci Resolve video exports became 30% faster. Adobe Lightroom’s AI Denoise went from nearly 3 minutes to just 18 seconds, a roughly 10x speed improvement. If you use your handheld for creative work, the eGPU pays for itself quickly in time saved.

Keep in mind that Thunderbolt connections typically lose 10% to 20% of the GPU’s native performance due to bandwidth limitations. OCuLink reduces this penalty to around 5% to 10%. Thunderbolt 5 narrows the gap further. The CPU bottleneck in handhelds also means that high end GPUs will not reach their full potential until handheld processors become more powerful.

The Cost Factor: Is an eGPU Setup Worth It

Let us break down the real cost so you can decide if this investment makes sense for your situation.

A Thunderbolt eGPU enclosure typically costs between $250 and $400 for a full size unit without a GPU. The Razer Core X V2 with Thunderbolt 5 sits at the higher end of this range. Budget OCuLink adapters and DIY solutions can cost as little as $50 to $100, though they lack features and protection.

The GPU itself is a separate cost. A mid range card like an RTX 4060 costs around $300. A high end card like an RTX 4070 Ti Super runs about $700 to $800. Since mid range cards offer the best value for handheld setups due to CPU bottlenecks, you can keep this cost reasonable.

All in one eGPU docks that include a built in GPU range from $500 to $1,500. The 2025 ASUS ROG XG Mobile with a built in GPU and Thunderbolt 5 is a premium option. The OneXGPU with a Radeon RX 7600M XT was priced around $700 to $760.

Compare this to buying a separate desktop PC. A capable gaming desktop costs $800 to $1,200 for a mid range build. The eGPU route costs a similar amount but gives you the flexibility of a portable handheld plus desktop power when docked. You also avoid maintaining two separate systems with two separate game libraries.

The eGPU approach is most cost effective if you already own a compatible handheld and want to extend its usefulness. It is less cost effective if you are buying a handheld specifically to pair with an eGPU, because the total cost approaches or exceeds a standalone desktop.

Future of eGPU Technology for Handhelds

The eGPU space is changing quickly. Thunderbolt 5 adoption is accelerating, and new enclosures using this standard are entering the market. With 80 Gbps bandwidth, the performance penalty over a direct PCIe connection shrinks to a much more acceptable level.

OCuLink is also gaining momentum. More mini PCs and a growing number of handhelds now include OCuLink ports. The standard offers excellent performance at a lower cost than Thunderbolt. As more manufacturers adopt it, expect a wider selection of enclosures and adapters.

Handheld processors themselves are getting stronger. AMD’s Ryzen Z2 series and Intel’s upcoming mobile chips promise higher CPU performance at the same or lower power levels. This directly reduces the CPU bottleneck problem that currently limits eGPU performance on handhelds.

New PCIe 5.0 based eGPU solutions are also on the horizon. These will double the bandwidth of current OCuLink setups, making even high end GPUs like the RTX 5090 viable in external configurations. Combined with faster handheld CPUs, the next generation of eGPU setups should deliver performance much closer to a traditional desktop.

The trend is clear. The gap between portable and desktop gaming is shrinking every year. Within a few product cycles, a handheld plus eGPU combo may genuinely replace the need for a separate gaming desktop for most users. The key is investing wisely today in standards and hardware that will remain relevant.

Quick Tips for the Best eGPU Experience

A few practical tips can make the difference between a smooth experience and hours of frustration.

Always use the shortest cable possible. Longer Thunderbolt cables lose signal quality. A 0.5 meter cable performs better than a 2 meter cable, especially at Thunderbolt 5 speeds. For OCuLink, use a cable under 1 meter for best results.

Keep your handheld plugged into power or use an enclosure with power delivery. eGPU setups draw significant CPU resources. Running on battery throttles the CPU and reduces performance. A powered connection keeps the handheld running at its maximum TDP.

Update everything before your first eGPU session. This includes Windows, your handheld’s BIOS/firmware, Thunderbolt controller firmware, and all chipset drivers. Many eGPU issues trace back to outdated firmware.

Set your Windows power plan to High Performance. The default Balanced plan may throttle the CPU during gaming. Go to Control Panel, Power Options, and select High Performance or create a custom plan with minimum processor state set to 100%.

Disable the integrated GPU in Device Manager if you are only using an external monitor. This forces all rendering to the eGPU and eliminates any confusion about which GPU is active. Be sure to re enable it before disconnecting the eGPU.

Run a quick benchmark after setup. Use 3DMark or Unigine Heaven to verify that the eGPU is performing as expected. Compare your scores to published benchmarks for the same GPU. If your numbers are significantly lower, revisit your driver and cable setup.

Frequently Asked Questions

Can I use an eGPU with a Steam Deck?

The Steam Deck’s USB C port does not natively support Thunderbolt or USB4 with PCIe tunneling. Standard eGPU enclosures will not work without hardware modifications. Some users have attempted workarounds using the M.2 SSD slot inside the Steam Deck with an external adapter, but this voids the warranty and is not reliable. Other handhelds like the ROG Ally, Legion Go, and AYANEO devices offer much better eGPU support out of the box.

How much FPS improvement will I get with an eGPU?

The improvement depends on the game, the GPU, and the connection type. In general, expect a 50% to 200% increase in frame rates for GPU heavy games. Tekken 8 doubled from 31 to 60 FPS with a Radeon RX 7600M XT. Risk of Rain 2 more than doubled from 62 to 130 FPS. CPU heavy games will see smaller gains because the handheld’s processor remains the bottleneck.

Is OCuLink better than Thunderbolt for an eGPU?

OCuLink offers higher raw bandwidth (64 Gbps vs 40 Gbps for Thunderbolt 4) and lower latency. It typically delivers 5% to 15% better GPU performance than Thunderbolt in benchmarks. However, Thunderbolt supports hot swapping, has wider device compatibility, and offers power delivery through the same cable. Thunderbolt 5 at 80 Gbps closes the bandwidth gap significantly. Choose based on what your handheld supports and your priorities.

Do I need an external monitor for an eGPU?

An external monitor is not required but is strongly recommended. Routing the eGPU output back to the handheld’s internal screen creates a round trip that consumes extra bandwidth and adds latency. This reduces performance and can cause stuttering in some configurations. For the best experience, connect a monitor directly to the eGPU’s HDMI or DisplayPort output.

Will any GPU work with any eGPU enclosure?

Most full size eGPU enclosures accept any standard desktop GPU that fits physically. Check the maximum GPU length the enclosure supports and verify that the internal power supply provides enough wattage. A 300W GPU needs an enclosure with at least a 450W to 500W power supply. Compact or proprietary enclosures like the ROG XG Mobile use built in GPUs and do not accept third party cards.

Can I charge my handheld through the eGPU connection?

Many Thunderbolt eGPU enclosures support USB Power Delivery through the same cable that carries the GPU data. This means you can charge your handheld while gaming. Check the enclosure specifications for the wattage it delivers. Most provide 60W to 100W of charging power. OCuLink connections do not carry power, so you will need a separate charger.
