    - accurate: differs 0.02V from my meter. - tip: a charging phone adapter can get very hot at the connector (50C+!). to prevent heat to the tester use a usb extender cable.

    Nice little gadget! Well backlit there's all of a sudden 2 rows of data staring at me, quickly changing the numbers to keep it interesting. Will be of good use with (too many) battery chargers, power banks, external HD's and solar panel chargers.

    Sehr gutes Gerät. Mit einem Belastungswiderstand kombiniert kann man auch sehr gut die Kapazität von Powerbanks feststellen.
