Along with the power bank, the UP10 comes with a branded anti-tangle USB charging cable, a user manual Additionally, for those purchasing the product from outside the US, there will be a 3-pin UK mains adapter included.

Build Quality and Design

The ROMOSS UP10 Power Bank is shaped like a miniature suitcase. I’ve seen this design before on theZendure A8 (currently at the top of my best high capacity power bank list).

On its left edge is a single button that can be pressed to start a charge or display the remaining battery life. This is indicated by four LED lights above the button, each one signifying a charge of 25%.

The UP10 has two USB ports on its top edge. Each port is identified with a single or double lightning bolt symbol. One of the ports has a max output of 1A, while the other provides a 2.1A charge.

This is handy for charging portable devices that specify a lower charge rate.  I have a number of action cameras that insist on a 1A Max input.

Most power banks these days advertise ‘smart ports’ which automatically adjust their output to suit the connected device. For those that are a little dubious about the reliability of this feature may prefer the manual option offered by this device.On its left side, neatly tucked into the body of the device is the UP10’s most unique feature – an integrated wall adapter. By default, this will suit a regular 2-pin US socket.

The UPower Power Bank has a built-in mains adapter


The pins flip down and click in place, allowing the power bank to plug directly into a wall socket.For UK customers, there is a standard UK plug adapter that slides securely over the pins.

The overall design and build quality is fantastic. The housing feels robust and all the components fit together with precision


The ROMOSS UP10 features pass-through charging technology.This means that you can plug the power bank into the wall and thenconnect your devices. They will begin charging as if connectedto a regular mains adapter.

Once complete, the UP10 will automatically stop charging them and begin recharging itself. This allows you to safely charge up to two devices, as well as the power bank, from a single socket.



If you’ve watched my demo video you’ll already know how well the UP10 performs. It has the best efficiency rate I’ve seen from a 10000mAh power bank. I time-lapsed it charging my Galaxy S7 edge and it managed an impressive 2.4 charges. It’s achieving a whopping 84% efficiency, this is way above the average. Most of the 10000mAh power banks I’ve tested have struggled to provide two full charges.


The ROMOSS Upower 10000mAh power bank is a quality product. It’s well presented, well designed and performs way above expectations. If I ever get around to making a best 10000mAh power bank list, I would not hesitate to place this right at the top.
