meaningful unit for a small price

Why ichs me buy? Well, 2 iPhones broken, diagnostic surge. 10 different chargers at home which you do not want to throw away all in such a case. So buy the PortaPow, measured and identified the culprit. The charger for the car gave out spikes to 21 volts and has destroyed my phones.

The charger is doing so, what it should: it measures voltages and can show the power consumption of your device. It does so reliably and accurately. I measure each charger, since I own the PortaPow that gives me after 2 defective phones security, it is also interesting if you can see, record how much power the connected equipment. The only connection option of PortaPow is via USB, so it can nciht to electrical outlets, etc. be connected. But it should be clear.

Buy recommendation for all who need an instrument!
