Very useful to assess charge rates etc.. “Input” and “Output” are clearly marked, but i wish it could be used in both directions. The “Input” is the male cable so it can only connect to a voltage source that has a female plug. If the source has a built-in male USB cable, then this wont work without an adapter. Also you can’t mix USB sources - like USB-C input to USB-A output. There are adapter cables to solve these problems, but it would be really useful if the meter had this flexibility. Overall, I”m very happy with it. ## Frequently Bought Together - Klein Tools ET910 USB Power Meter and Tester, USB-A Digital Meter for Voltage, Current, Capacity, Energy, Resistance, Max Current - Treedix USB Cable Tester Board USB Cable Checker Data Wire with Acrylic Case Charging Test Data Line Type-C Micro Type A Type B - MakerHawk USB Multimeter USB Voltmeter Ammeter Load Tester USB Voltage Current PD Battery Power Capacity Charger Type C Meter Tester LCD Display Cable Resistance QC2.0/3.0/4.0 N10 1.44 Inch Screen --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/89720046-klein-tools-et910-usb-power-meter-and-tester-usb-digital](https://www.desertcart.dk/products/89720046-klein-tools-et910-usb-power-meter-and-tester-usb-digital) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-24*
