It's hard to believe that the cost of this unit is as cheap as it is.A must to have if you own several different USB chargers and you want to know which ones can be thrown away because they are garbage and others that perform very well. ### ⭐⭐⭐⭐⭐ This device is very useful. *by K***R on Reviewed in the United States on November 21, 2017* This is simple to use. I have used this to check all my USB chargers and to identify charging cables that limit the charge current. The end that plugs into the charger will go in backward or frontward so the indicator is always facing you. --- ## 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.hk/products/37171285-portable-digital-usb-multimeter-dc-3-30v-0-5-1a](https://www.desertcart.hk/products/37171285-portable-digital-usb-multimeter-dc-3-30v-0-5-1a) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-20*
