Let’s say “what’s up” to the Watt’s Up Meter! The Watt’s Up makes it easy to measure a project's charge/energy demands and battery capacity, capture peak power and measure high currents. All functions missing from most multimeters. An all-in-one digital DC amp meter, Watt’s Up measures current, voltage and time — and from those measurements calculates peak current, peak power, minimum voltage, power (W), energy (Wh)and charge (Ah) values for you, in real time, for the circuit in which you connect it.
The Watt’s Up is perfect for situations when you need to evaluate project current and energy needs, prevent peak currents damaging a battery, for operating motors, balancing battery cells, setting cutoff voltages and more. Each Watt’s Up has been equipped with two sets of wires marked “SOURCE” and “LOAD” as well as a 16x2 black-on-green sharp LCD screen.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Based on 3 ratings:
Very easy to use and the unit was accurate. Will be built into some test equipment very soon.
Works as advertised. Gives you the information you need to make decisions on device under test.
Built three Ebikes and have used these on all. Very useful to keep up with battery voltage and Watt-hours which is the best way to determine just how much more charge you really have.
