Not every trip needs a big power bank. For a night or two away, a couple of phone charges is plenty, and a smaller power bank saves space and weight.

The Kings 10,000mAh Lithium Portable Power Bank is the small one of the two Kings power banks we carry. Compared with the Kings 20,000mAh power bank, it’s much simpler and smaller: 37 Wh in a blue case that weighs only 201 g, with no screen and no torch.
What You’re Getting
A 10,000 mAh (37 Wh) lithium power bank from Adventure Kings in a blue case, with a USB-A output, a USB-C port for charging in and out, a micro-USB input and four LED lights for the power level. It comes with a 50 cm USB-C cable.
The good
- Compact: 135 × 67.5 × 15 mm and 201 g
- 18 W fast charging from both USB-C and USB-A
- Charges two devices at the same time
- Four LED lights show the power level
- About 2 phone charges
The not-so-good
- Capacity is not massive
- Still quite bulky for a 10,000 mAh power bank

| Outputs | 1 × USB-A1 × USB-C |
| Inputs | USB-CMicro-USB (5 V/2 A, 9 V/2 A) |
| Charge level | 4 LED lights |
| Output power | Up to 18 W per port (5 V/3 A, 9 V/2 A, 12 V/1.5 A) |
Ports and charging
All three ports sit on one end, each with its label printed on the case: a micro-USB input, a USB-C port and a USB-A output. The USB-C port works both ways, so you can charge a phone from it and recharge the power bank through it.
Both the USB-C and the USB-A port are capable of 18 W fast charging, and you can charge two devices at the same time. The power bank itself takes up to 18 W in through USB-C or micro-USB.
It gives you about 2 phone charges. That’s half of what I get from the Kings 20,000 mAh, which is what you’d expect from half the capacity. The capacity is not massive, so for longer trips away from the car you’ll want something bigger or a way to recharge it.
Charge level
There’s no screen on this one. You see how much power you have left with the four LED lights: press the button on the side and they show the power level.
Size & Weight
The compact size is the reason to pick this one. It measures 135 × 67.5 × 15 mm, about the footprint of a phone, and weighs 201 g on my scale. That’s a bit more than half the weight of the Kings 20,000 mAh (377 g), for half the capacity.
Next to the two 20,000 mAh power banks we have, the Kings and the VRURC, it’s the slimmest of the three. For a 10,000 mAh power bank it’s still quite bulky, though: there are smaller ones with the same capacity. This would be a good option for a solo hiker who needs to save space on short trips.
Kings 10,000mAh vs 20,000mAh
Kings sells this power bank in two sizes, and I have both. Here’s how they compare.
| Kings 10,000mAh | Kings 20,000mAh | |
|---|---|---|
| Capacity | 37 Wh | 72 Wh |
| Phone charges | About 2 | Almost 4 (iPhone 16) |
| Weight | 201 g | 377 g |
| Size | 135 × 67.5 × 15 mm | 180 × 80 × 22 mm |
| Outputs | 1 × USB-A, 1 × USB-C | 2 × USB-A, 1 × USB-C |
| Fastest output | 18 W | 45 W (USB-C) |
| Charge level | 4 LED lights | LCD screen with volts and amps |
| Torch | No | Yes |
| Low Power Mode | No | Yes |
| What I paid | About $30 | About $100 |
| Our score | 8.3 | 8.5 |
The 10,000 is much simpler and smaller, and costs about a third. The 20,000 gives you twice the charges plus a screen, a torch and a Low Power Mode. See the Kings 20,000mAh power bank review for more. For all the power banks we’ve tested side by side, see our best camping power banks guide.
Conclusion: Kings 10,000mAh Lithium Portable Power Bank
The Kings 10,000mAh power bank is much simpler and smaller than its 20,000 mAh big brother. There’s no screen and no torch, just about 2 phone charges, 18 W fast charging from two ports and four lights for the power level, in a case that weighs 201 g. The capacity is not massive, and it’s still quite bulky for a 10,000 mAh power bank. I paid about $30 for it. If you need to save space on short trips, it’s a good option.
A simple, compact 10,000 mAh power bank: 201 g, about 2 phone charges and 18 W fast charging from two ports.

- Solo trips
- Hikers
Yes, if you want something small. I paid about $30, and for that you get about 2 phone charges and 18 W fast charging in a case that weighs 201 g. If you need more charges, or a screen and a torch, look at the Kings 20,000 mAh.
