I Like Them
I have several items with internal rechargeable batteries that have NO Charge Level Indicators. Instruction manual just says to charge for 2 hours. Is that enough???? Is that TOO much????With these, I can tell when they are fully charged.These work so well, I use them for everything I charge.

VERY informative as to how much current.
VERY informative as to how much current. I have these inline to tell how much current is going in to my speakers while playing and charging. ALSO charging rate of any other items that I am charging. GREAT for checking chargers and cables.

does the job, one-way only
This tester's biggest disappointment is that it's limited to a single direction, and as a result it can be very award to test on certain devices without extension cables as you'll need the tester plugged into the power supply then the device in question plugged into it and for my use case scenario the opposite would be more ideal.That may just be a me problem though.Display on it is ultra clear and it seems to be recording accurate totals. Using it to test power banks that I had suspicion were overrating themselves (and they were BY THREE TIMES CAPACITY!), so I'm sure this will be seeing plenty of use in the future.

Marvelous
This little device is perfect. It allows me to monitor a medical device to make sure the power stays in. Perfect! Great price, too.

Uncertain on accuracy but I love these little buggers!
The red current reading is a little hard to read in bright light. But makes testing little solar powered gadetry so convenient!!

Very Handy to Have.
I use these Keweisi meters for so many things. Obviously my small portable solar panels to get the best sun and to monitor charging etc. I have couple of other usb meters that have Bluetooth and check capacity but just having these handy is a times saver. I really like the red and blue display,it is really clear and bright. I have these USB test leads that use with the Keweisi multimeter to quick test my lithium batteries but it only works on 3v or up to 30v. I plan to get a couple more. If you got the right USB adapters there is allot you can do with them. Thanks Keweisi

Beware
After 31 days, one of the meters, started showing only a single digit for AMPs.Amazon will do NOTHING, after 30 days
