Lipo Rider Plus Isn't 5V!

The Lipo Rider Plus doesn’t output 5V, but more like 4.8V with my measurements.
I appreciate most USB devices function at this lower voltage but I require the stated 5V (or perhaps even slightly more) so this is quite disappointing.
Is it possible to replace a particular component and tweak this output?

Yes, you are right. It’s depend on the PMIC, can’t replace any component to rise up.

Damn that really really sucks. Wish I hadn’t bought 5 (shipped internationally)! Can’t really return them for a refund :angry:
