Hello !
I’d like to buy USB Tester - I see, that some of You recommend Xtar VI01 , but it seems to have quite high resistance that significantly reduces voltage (i.e. by 0,39V at 2A). It worries me a bit, but I can see, that even professional USB tester, like PortaPow Premium reduces voltage (by 0,33V at 2A).
After reading every USB tester review here I think, that this ebay USB meter will be best choice - it seems to be accurate enough and it has lowest resistance, at 2A it reduces Voltage by only 0,26V. As there are more accurate testers, but with higher resistance, here is important question for me - how does the reduced voltage affect charging - can it cause damage to the battery or so? Will ebay USB meter be a good choice, or should I buy more accurate tester but with higher resistance?
Regards
Michal
