This USB Multi-meter plugs directly into any USB socket or Micro-USB charger or cable. It displays on the screen the voltage, current and capacity. Acts as both a vol and amp meter. All three are shown at the same time so there is no need to switch between screens. It is powered when you plug it in so no batteries are needed. Backlit screen will let you see it in low light conditions. Will handle up to 3.5A which is more than enough to test any cell phone or tablet. The monitor is suitable for 0-2.5 Amps, and 3-20 Volts and has an accuracy better than 1%. It can also give you a rough estimate of the capacity of the device you are charging. Made by Muker.

"Data Checking Mode" is entered by double clicking the button really fast. When in this mode the screen blinks and you can select the current data bank you are using by single clicking the button really fast. Each time you single click the button, it moves to the next data bank and then rotates back to the fist bank (bank 0) if you click it at the last bank (bank 9). You exit "Data Checking Mode" by double clicking the button really fast.

36:T5ad,Functionality wise it's great, with a nice clearly readable screen. It reads out voltage, current and mAh consumed, with the latter seeming to have 10 nonvolatile memory positions with which to store totals.It also features a useful MicroUSB port allowing you to test voltage drops across cables instead of only at the source port like many USB meters (combined with a USB load tester for instance this is a great way to find feeble or bad USB cables that would cause phones to charge slowly).However... I'm less enthused about how mine came equipped with a dud cable itself!!! It sort of works but with lots of random voltage drops and at certain angles the power cuts out entirely. Needless to say that's useless on a device that's supposed to
