Xtar V101 USB Current/Voltage Detector.
The V101 measures the USB output voltage of a power bank or battery charger.

I found a different type that displays voltage and current at the same time. (2 displays on board.) In as much as I like that idea I found it to be quite inaccurate for both voltage and current readings - so it's pretty pointless.
This Xtar V101 has been tested by lygte-info.dk and it measures voltage and current very accurately. I may not like the Xtar single display design that alternates between current and voltage readings as much - but at least the Xtar model does what it is supposed to do: gives you accurate voltage and current readings.
Get this one, don't try to save a buck or two and then have to buy the V101 anyway.

I wanted to check current on a couple different chargers and this works fine. Good addition to the kit.
