Review on Charger Doctor: USB Tester & Multimeter for Solar Panel Chargers & USB Devices - Troubleshooting Tools and Battery Monitor by Eric Wohlman

Sometimes you just need to know E and I. You have to find out the rest yourself. And with that, you can watch the milliamps (mah for those who don't know what they're talking about or what they're for.) go down to zero and then the charge indicator on all my devices goes out. Engineer and I don't work in IT. I didn't get it for free or any other reason. Can I recommend it? Absolutely and unconditionally. PS My apologies to everyone who was offended by my "Makhov" comment. I'm old and I feel justified in complaining from time to time that the English language has gotten so dirty.
