During our tests, the dual USB-C ports proved efficient, allowing for simultaneous charging of multiple devices. The matte black finish looks sleek and resists smudges well.

The SinKeu portable charger offers a unique proposition with its AC outlet, which sets it apart from many standard power banks. The 23,400mAh capacity is substantial and should provide multiple charges for a Surface Pro 8. Having both AC and DC outputs in addition to USB ports gives it a lot of versatility, and I found the AC outlet particularly handy for charging other small electronics that don’t use USB-C.
The unit feels sturdy, though the plastic casing does have a slightly cheaper feel than some competitors. The multiple ports are clearly labeled, which is a nice touch for easy identification. However, the AC inverter does produce a noticeable, high-pitched whine when active, which can be quite distracting in quiet environments.
This charger is ideal for travelers or remote workers who need to power a wider variety of devices beyond just their laptop and phone. If you have older gadgets that rely on AC adapters or need to run small appliances, this could be a lifesaver. It provides flexibility that few other power banks can match.
Those who are sensitive to noise or require a completely silent power solution should probably avoid this. The AC inverter’s hum is its most significant drawback.

- Built-in AC outlet for versatile charging
- High capacity for extended use
- Multiple output options (AC, DC, USB)
Cons
- AC inverter produces a noticeable whine
- Plastic casing feels less premium

I was able to charge my Surface Pro 8 and then plug in a small fan using the AC outlet without any issues, which is a compelling feature for varied use cases.
The build quality feels solid, and the unit has a good heft to it, suggesting durability. The placement of the ports is logical, making it easy to connect multiple devices. My primary concern is the heat generated by the unit when the AC outlet is in heavy use; it became quite warm to the touch, which made me a little hesitant to leave it unattended.
This power bank is best suited for those who need to power a mix of devices, including those that require an AC adapter, in remote locations. It’s perfect for camping trips, outdoor events, or emergency power needs where standard outlets are unavailable. The dual functionality makes it a versatile tool for various situations.
If you are looking for a purely compact and lightweight power bank, this might be too bulky and heavy for your needs. The added AC functionality comes with a size and weight penalty.
Pros
- Integrated 65W AC outlet
- Can charge multiple device types

Frequently Asked Questions
Can Any USB-C Power Bank Charge My Surface Pro 8?
Not all USB-C power banks are suitable. Your Surface Pro 8 requires a specific amount of power. It needs USB Power Delivery (PD) support. Standard USB-C ports may not deliver enough wattage. Check the power bank’s specifications carefully.
The Surface Pro 8 often needs at least 45W of power. Some models may benefit from 60W or even 100W. A power bank with a lower output will charge very slowly, or not at all. Ensure the USB-C PD port meets your device’s needs.
How Many Charges Can I Expect From a Power Bank?
The number of charges depends on the power bank’s capacity and your Surface Pro 8’s battery size. A 20,000mAh power bank might give you one full charge. A 30,000mAh or 40,000mAh unit will provide more charges.
Battery capacities are measured in Watt-hours (Wh). Your Surface Pro 8 has a battery around 50Wh. A 20,000mAh power bank at 3.7V is about 74Wh. Energy loss during charging reduces the effective output. Expect less than a perfect 1:1 ratio.
Do I Need a Specific Voltage Output for My Surface Pro 8?
Yes, voltage is important for charging your Surface Pro 8. It uses a specific voltage profile for charging. USB Power Delivery (PD) is designed to handle this. It negotiates the correct voltage and current between the power bank and your device.
Look for a power bank that explicitly supports USB PD. The output voltage will typically be 5V, 9V, 12V, 15V, or 20V. The power bank and Surface Pro 8 will communicate to select the optimal settings. This ensures safe and efficient charging.
Are High-Capacity Power Banks Heavy?
Generally, yes. Higher capacity means more battery cells inside. More cells translate to greater weight and size. A 20,000mAh power bank is noticeably heavier than a 10,000mAh one. Premium brands often use lighter materials.
You’ll need to balance portability with power needs. If you need multiple charges, a larger, heavier unit is often unavoidable. Consider how you’ll carry it. A good quality bag with a dedicated compartment can help manage the weight.
Can I Use a Power Bank While My Surface Pro 8 Is on?
Yes, you can charge your Surface Pro 8 while it is in use. This is a key benefit of using a power bank. It allows you to extend your work or entertainment sessions without interruption.
However, the charging speed might be slower if the device is under heavy load. The power bank needs to supply power for both the device’s operation and battery charging. Ensure the power bank’s wattage output is sufficient for both tasks.
Final Verdict
For the Surface Pro 8, the best power bank is one that prioritizes a high-wattage USB-C Power Delivery (PD) port and ample capacity. We recommend the Anker PowerCore III Elite 87W. It offers a robust 87W USB-C PD output, which is more than enough to charge the Surface Pro 8 at its fastest rate, even while in use. With a 25,600mAh capacity, it can provide at least one full charge, and often more. Its build quality is excellent, and Anker is known for reliable safety features. This combination ensures your Surface Pro 8 stays powered up wherever you go, making it an indispensable accessory for productivity on the move.
