Works perfectly. Going to make life a lot easier in the future. Using it for a wi-fi ups from a lithium battery and had no problems with efficiency. You just have to make sure you battery or power bank can supply 2amp plus a bit. Thank you
haven't tested them yet. looking good so far.

Small pieces but powerful effect, purchased again and waiting to receive. Thanks Banggood.
Aus den 3,7 V vom LiPo_Akku kann man einfach hochtransformieren und die Ausgangsspannung ist sehr stabil.
Working great
Works fine
The module works well with a 4V input and up to 18V output. I did not get 28V but luckily I do not need it. I have only used 1 module and will update the review as I use the others. I used it with 12V 1.3 A output to date.
