## Customer Reviews

### ⭐⭐⭐⭐⭐ Does exactly what it says. Good purchase.
*by D***T on 1 April 2021*

I use this for a DIY power bank and portable entertainment system. It’s relatively simple to set up but the instructions could do with a little more description on what each function does.Accuracy seems to be good but I can’t say for certain as I’ve not tried it on a brand new battery yet.

### ⭐⭐⭐⭐⭐ Very good unit.
*by C***R on 8 September 2020*

This unit has replaced an old one which plugs in the power socket, the screen is bright and clear the instructions which do not come with the unit take a little while to understand, which you to read on site hopefully it will give good service.

### ⭐⭐⭐⭐ Very good little product
*by C***J on 15 July 2021*

Very happy with this product, appears to be working fine and having tested the battery with a proper meter it's reading the correct voltage. Upon switching on the trickle charger the voltage appears to increase and percentage looks about right.For anyone suggesting it simply reads 100% all the time needs to change the battery type. Mine was showing 100% for three days however upon changing battery type (it was set to 3x lithium battery's instead of 1x lead acid) indicator changed to 83%. To get into setting mode, hold the left button before inserting power cable.4 stars as it would have been better to have the power lead come out from underneath rather than the back as that had now made it harder to simply use sticky pads when mounting to a surface (cable in the way).Working well so far though.
