    In photos we see testing of a 1Amp power bank, and connected to the 12 in one USB tester voltmeter to accurately read the parameters. Second photo shows meter connected to a 3Amp high speed charger, though its a bit dark and blurry picture, I think we see the numbers OK. The supply was loaded up using the Star Trek Enterprise variable load. Now we need not be fooled by the exaggerated claims of inferior USB power products.

    works well, mind you I would say 11 and not 12, 12 in 1 tester as one of the 12 is a welcome screen mind you that could be me being picky, so yeah I would recommend this USB tester

    Testeur USB avec écran LCD assurant 12 mesures distinctes du courant électrique y traversant. L'affichage des données se fait par pression sur le côté latéral (mode d'emploi sur fiche produit). Offre des données précises pour un prix modique.
