Voltage Tester

it is good quality
Got this together with the solar charge controller/regular, very neat and handy testing tool!
Instead, it can be used standalone for almost all different types of uses, as long as it is USB!
Yes, you can test the voltage output of your computer, USB travel adapter, and the current of your phone being charged.
You can also use it to test a power bank! Yes, plug this to a fully charged power bank, then plug an empty-charged smartphone into the end of this tester, you will instantly know the current/voltage being delivered, AND the time plus the mAh!!!
It's a versatile USB voltage/current/capacity testing tool

5 stars SOOOOO USEFUL!!

Fast shipping
I seriously love this little guy! It looks so cool when it's lit up! Just plug it in to a USB power source and you get the voltage (V) coming out of the tester, the current (mA) being drawn from the power source by the load device
