Get This USB Power Meter on Amazon: http://www.amazon.com/dp/B015IN7L3M/?tag=miirii-20
Best When Used With a Constant Current Load Resistor Like This One: http://www.amazon.com/dp/B00X3HTHEM/?tag=miirii-20
A Good USB Power Monitor/Tester is a Great Thing to Have in Your Gadget Drawer, especially if you use a lot of aftermarket chargers.
There are a fair number of USB multi-meters on the the market, but I would definitely recommend getting one with mAh output capability. The cheaper ones like the DROK only show volts and amps and can’t tell you how much current you have used over time. With those cheaper ones you can’t test a battery bank to check and verify it’s capacity. That’s where this one comes in. It is one of the cheaper units that have mAh capability.
I have put it to the test along side my Amortek unit which I reviewed here: https://youtu.be/6Mc5SOMlDHw
This one is not quite as fancy as that one, but it costs $10 less. Once I figured out how to use it, I had no issues doing all the same tests I could do on the more expensive Amortek. So if you’re on a budget, buy this one and the SMAKN constant current load resistor (link above) for your testing. If you can afford the extra $10, go with the Amortek. This one still gets 4 out of 5 stars for being cheap and fully functional.
+ Displays Volts & Amps Accurately
+ Displays mAh to test battery banks for capacity and power used over time
+ Comes With USB Breakout Cable with Micro, Lightning, iPod Connector
+ Has Micro USB input for direct testing of Micro USB cables
+ Has 10 memory slots so you can store and come back for mAh data.
– Small Display
– Button Operation is a Little Tricky/Counter-intuitive
I will continue to use this meter in testing and have no trouble recommending it, just watch the video to learn how the memory function works.
