## Customer Reviews

### ⭐⭐⭐⭐⭐ It works great
*by P***E on 20 April 2025*

Its great. Does exactly what it should. 👍

### ⭐⭐⭐⭐⭐ Brilliant
*by B***E on 4 June 2025*

Amazing used several of these in our caravan to either replace throw away batteries, or to add extra USB power sockets, gives a stable 5 volts.

### ⭐⭐⭐⭐ Useful for adding power to USB data
*by C***K on 14 November 2025*

It works well as a way of adding additional current capacity to a data USB connection. Ideal for in car use such as with Android screens and other audio systems which provide a USB connection for a phone but insufficient power to charge the phone at the same time. For this it is good but a few more mA of power wouldnt go amiss - it provides enough power to stop the phone battery rapidly discharging whilst connected but not quite enough to fast charge the phone.
