The Romoss Arrow20 Powerbank body is made of PC+ABS plastic in which it makes it lighters as well. The material has more resistance to higher temperature than ordinary plastic. The overall body finish is matte.

The powerbank is packed with large capacity Li-Poly batteries inside. It has quick charge feature that lets you have it fully charged at just 13 hours or 6.5 hours if using a 2.1A adapter. It has 2 ports that can charge two devices simultaneously. The IC technology on this powerbank guarantees that even at less than 30% capacity, it can still charge two devices stably.

Ther is a LED indicator on the side for the estimate of the power left on this powerbank. Romoss also said that this powerbank has intelligent sleep that helps prevent losing it charge if not in use.

The powerbank is able to output 5V or 3.7V depending on the connected device which its chip automatically detects. Other features of this powerbank are as follows:

  • Overcharge protection
  • Over discharge protection
  • Over pressure, over current, over temperature, and over power protection
  • Short circuit protection
  • Reset feature
  • EMF protection

The powerbank isn’t so big at all. Although it is still bigger than an iPhone 6. Gripping it one hand is an easy task.

It weighs just 422g which is not very heavy, or maybe heavy for some, but it is still comfortable to hold even, thanks to the ergonomic design of curved housing.


With its price tag, I can say that the Romoss Arrow20 is a great choice for a 20000mAh powerbank. Romoss has already built its name in the power bank industry, and the competitive price tag, paired with the quality and design makes this power bank a must have for everyone who needs the extra juice for their devices.
