Review on Eversame Multimeter Chargers Capacity Banks Black by Joe Gilmartin

Works great! NOTE: This rating refers to the black version of the "USB Safety Tester" without a cable. There are 3 screens for cycling: 1) high voltage, high current, watts, total time, total amp hour, total watt hour 2) voltage of all 4 pins (v-, d-, d+, v+), resistance (probably between d- and d+), temperature, Time, Current3) ((redundant information on screen 1 and/or 2)) This meter will work with fast charge cables/power supplies that display a voltage > 5V. Voltage/resistance meter d - and d+ are great as they allow you to determine the capacity/type of charger connected. The screen is of very poor quality. The viewing angle says next to nothing, you have to look straight at it to read it. Connector A is reversible so you can plug it in either way (up or down) which is useful if you have a laptop/plug that would otherwise result in the screen facing away from you. Note that this makes the connector quite fragile as the plastic blade inside the connector is very thin and has 2 sets of pins on either side. Although the connector is reversible, the screen isn't one that lets you look at the screen, it's all upside down. .The mode button, when held down, also resets the cumulative timers and also emits a horrible beeping sound when doing so (the beeping sound also sounds when it is first turned on). I wish there was no beep, it's very annoying.
