Review on DROK Converter Mobile Battery Indicator by Dan Phillips

This module is so handy and useful that I had to order another one. I first ordered it for the Altoid Solar USB Charger. It boosted the current to 5 volts and was powerful enough to draw 2 amps and quickly charge my flagship phone. I then used it with two of my parallel connected window solar panels rated at 6 volts 583mA and it also boosted the voltage when the sun wasn't at its highest (5V 1A) and it didn't fail when it was exposed to 6.15V then I used it with a pair of 18650s to build a power bank. The great thing is the LED indicator and the amount of current it can deliver (great for devices with 2A fast charge!). Note that this module does not increase the current. So plugging it directly into a small solar panel will only increase the voltage. My next plan is to add 3 more solar panels in parallel to create a 2A output on my window and this panel will be key for sure!
