Charged my Galaxy Tab connected to Solar Panel – Will buy again This module is so handy and useful I had to order another one. I ordered it for an altoid solar usb charger at first. It stepped up the current to 5 volts, and was strong enough to draw 2 AMPs and power charge my flagship phone quickly. I then used it with two of my window solar panels in parallel rated 6 volts 583 mA and it also stepped up the voltage when the sun wasn’t at its highest (5v 1A) and didn’t fail either when exposed to 6.15V. Then I used it with a couple of 18650s to make a power…

2 AMP 5 Volt step up goodness Since I replace batteries, before they go dead, in my power hungry accessories like four inside/outside thermometers and other items around the home I wind up with a bunch of batteries that are low but not dead. I hate to throw them away so I ordered several battery holders to provide 6 or eight volts out of these low batteries. I plug them into the USB DC-DC converter to power my USB powered/charged units. This little device squeezes out every drop of power in them so when I throw them to the…
