This wiki has been updated 11 times since it was first published in December of 2018. One of the most useful aspects of the relatively modern USB Type-C protocol is its ability to charge a huge range of products at a precisely controlled wattage. Because not all batteries, devices, and wall warts are created equal, many users turn to a power meter to verify the rate at which they're transferring electricity. The right tester will help you refuel your phone or laptop without worry. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.

Editor's Notes

December 31, 2020:

To be clear, it's important that you use only reliable devices with your USB-C charging equipment, lest they get damaged by faulty electronics. To that end, we've narrowed it down to just a few options that are highly dependable. At the top of the list is the Klein Tools ET920, which looks, feels, and operates like a professional-grade product. The MakerHawk TC66, on the other hand, looks almost like a DIY project, but in fact provides even more information than the Klein. The Flight-Sky Multimeter provides almost as many useful statistics, plus it costs about half as much as most others.

If you don't need all that functionality and would rather have something more sleek, the Satechi TCPM and Kavalan Indicator are both viable choices.

USB type C was developed for added convenience, data transfer, and charging capabilities in the newest and fanciest devices. As a relatively new standard, however, not every cable, charger, battery pack, and phone plays nicely together. An in-line tester like the Jokitech will give you all the info you need, and you won't have to carry any extra cables or adapters with you. The Drok will require an additional USB-C cord, but it's also a multipurpose meter that serves a range of advanced functions, much like both MasterHawk options. The Eversame is similarly versatile, and might last a little longer, as unlike some, it's fully encased in a durable plastic body. If you're only working with power up to 18 watts, and only in one direction, you should be able to get by using the Soonhua, which is incredibly inexpensive, and also especially streamlined.
