Great product! - Great product that outperformed my expectations. It charges my Vape batteries quickly, and to their actual full capacity. They stay at 100% for a long time in my vape that I usually run at about 220. They hold their charge for a long time even in storage. I’ve had two other chargers prior to this one, and this IMREN 4 bay charger is the best yet. You can use it for various other types of rechargeable batteries, and I’ve received the same results. Great product for a great price. This is one of the best purchases I’ve made. Review: Good charger for price. - Great for recharging vape batteries. I have a 200 watt mod that does charge batteries itself but only charges them to 3.7v. This charger charges them to 4.2v which makes my batteries last a lot longer at this charge voltage with not needing to charge them for nearly 2 days of continuous use. ## Features - 【18650 Battery Charger】-The 18650 Charger for -1.2V Ni-MH Ni-Cd A/AA/AAA/AAAA 10440 14500 14650 16340 17335 17500 18500 18350 18650 18700 20700 21700 22650 25500 Battery - 【Smart 21700 Battery Charger】-The 18650 battery charger have a Single battery charging capability,You can charge any number of batteries without charging in pairs.

Great product! *by C***Y on September 24, 2026* Great product that outperformed my expectations. It charges my Vape batteries quickly, and to their actual full capacity.

Great product for a great price. This is one of the best purchases I’ve made. ### ⭐⭐⭐⭐⭐ Good charger for price. *by A***O on September 2, 2026* Great for recharging vape batteries. I have a 200 watt mod that does charge batteries itself but only charges them to 3.7v. This charger charges them to 4.2v which makes my batteries last a lot longer at this charge voltage with not needing to charge them for nearly 2 days of continuous use. ### ⭐⭐⭐⭐⭐ Works well, and simple *by T***R on September 24, 2026* Works well with lithium batteries, even the flush-end ones. For NiMH, doesn't quite charge to full voltage as my other chargers, but the difference is minimal. It's simple, with only one button to control current. Easy to use. Seems a good value for the function. I'm definitely happy with the purchase. ## Frequently Bought Together - IMREN 18650 Battery Charger,21700 Battery Charger for 3.7V 14500 10400 18500 18350 18650 18700 20700 21700 22650 26650 Li-ion Battery,1.2V Ni-MH/Ni-Cd Battery,4 Bay 18650 USB C Charger - Imren 9V Rechargeable Lithium Batteires, 3600mWh USB 9 Volt Li-ion Rechargeable Battey Long-Lasting，with 4-in-1 USB-C Charging Cable, 1.5 Hrs Fast Charging for Smoke Detector/Alarms,4 Pack --- ## 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.hr/products/357262351-18650-battery-charger-21700-battery-charger-for-3-7v-14500](https://www.desertcart.hr/products/357262351-18650-battery-charger-21700-battery-charger-for-3-7v-14500) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-09*
