Very rare, but you don’t want to sell an $80k 5th wheel hauler that has a plug that won’t charge your phone!I’ve only played around with the pass thru feature so far, bought it for testing USB ports, which it does great.This isn’t for everyone, definitely a techie gadget. I only wish it had its own power so that I didn’t have to wait for it to ‘boot’ before testing. Some RVs have several ports throughout.I would buy again but I shouldn’t ever have to. It’s of good Klein quality. I like it. ### ⭐⭐⭐⭐⭐ Excellent *by on Reviewed in Canada 16 May 2021* Great Klein product. Test feature is a huge plus. I Bought it to test loads on my usb/ plug and usb power supplies laying around .Does everything it advertises, easy to use ### ⭐⭐⭐⭐⭐ Convenient way to test USB chargers! *by on Reviewed in Singapore 3 May 2022* I bought this tool (ET910) to help a client check that the USB input source his board is drawing, is capable of providing 5V 3A under stress conditions. In less than a minute, I simulated currents of 0.5A, 1A, 2A and 3A, and demonstrated that the input source isn't capable of providing 2A or more (plus that the voltage will drop to 3V and provoke other failures). Such convenience! We quickly tested the other USB chargers he has and identified which ones he should use instead. Well worth the money! ## 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.no/products/145332217-klein-tools-et910-usb-power-meter-and-tester-usb-digital](https://www.desertcart.no/products/145332217-klein-tools-et910-usb-power-meter-and-tester-usb-digital) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-19*
