An extremely useful tool to have in your bag

By: Siddhartha Sen on 02/21/2018

An extremely useful tool to have in your bag. The only nit that I can pick is that for devices which have the USB c on the right side , the reading faces away from you. But honestly if that is the only nit I have , I really shouldn't complain . Great tool and good build quality.
Effective and less expensive

By: D. Arthur on 01/11/2018

Very effective meter. Unlike micro, mini and lightning cables, USB-C cables are bidirectional. When I plug my power pack to a power source it charges, when I plug it to my phone it discharges. This meter shows an arrow telling which direction the power is flowing. In addition to showing volts and amps it also shows total Mah since it came on - if you know your battery capacity that means you have some idea what percent charged or discharged it is, even if the device is off. I would not call this meter rugged, but it has not shown any signs of wear or breakage yet. Some reviews mentioned breaking it: I am guessing that comes of plugging and unplugging it without enough care. Mine is plugges into the power pack: the far end of the cable goes either to the wall or to the phone but the power pack end just stays connested, so I am not expecting any wear on the meter. Finally, I was surprised at how much more USB-C power meters cost than USB-A power meters. But this one cost less than most.
Great USB-C Volt & Amp Meter with Power Delivery Spec!

By: Joey Riz on 11/14/2017

This was a great tool I used while testing various USB-C devices to see if they were charging at the rates they should. This was super easy to use and the screen was nice and easy to read. It uses the power delivery specification so it will work when testing all of those devices. Highly recommended if you are using it any reviews!
Love the company and their products.

This is a very nice device and at a really good price considering what it does. I was impressed that it can handle current flow in either direction. The display is nice and easy to read, and there's a nice visual effect when it updates (update sweeps up from the bottom). I'm really impressed with Gearmo.
