    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

    From the 3.7 V of the LiPo battery you can easily transform up and the output voltage is very stable.

    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.
