I bought this for camping, and specifically because it will work with my external battery pack, so I have now consolidated my charging requirements into a single form-factor for cable/battery/charger/phone. The only thing I would have done differently would be to add the capability to dim or disable the charging LED, since it is SO bright. It's a small, blue, 3-segment charge indicator, but you could nearly light up your whole tent with the LEDs. Little bit of gaffer's tape takes care of that. Very pleased with the purchase, and would buy again, if needed. Nitecore produces top-notch products that won't let you down.

The 3 LEDs give an indication of the state/percentage of charge, I like that. I noticed the description and reviews mention a Micro-USB port, but mine came with a USB-C port (I’m guessing it’s a newer version). ## Frequently Bought Together - Nitecore UI1 Single-Slot Intelligent Lithium-ion Battery USB Charger for 18650, 18350, 20700, 21700, 16340, 14500 and More,and LumenTac Battery Organizer - 2X Nitecore IMR 18350 NI18350A 700mAh 3.7V Button Top Rechargeable Battery (This is NOT a Replacement for CR123A) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/178169974-nitecore-ui1-single-slot-intelligent-lithium-ion-battery-usb-charger](https://www.desertcart.co.za/products/178169974-nitecore-ui1-single-slot-intelligent-lithium-ion-battery-usb-charger) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-01*
