BUT, the minimum charging current is 1A. RCR123 and 18350's fit great and will charge, but it is above the recommended charging current for the batteries. Oddly, it does .5A for nickel metal hydride. If you are limiting your use to 18650's or higher, you should be fine and it has worked well for these for me. But, be aware of this drawback despite the description, which includes these batteries.Positives:Small rubber feet on back to keep from sliding (this is missing from most little portable units)Reads out in percentages and calculates almost instantlyStrong spring and battery fits wellHas an off button (double tap the amp button to turn off display (my other portable units lack this) Negatives:No .5A charging option for Li-Ion.I like this unit better than the EFEST, because the efest has no readout to tell you what % your charge is as only a color change to say it's charged. The EFEST is very very cheap feeling. The BASEN takes several seconds to evaluate your charge percentage and then only displays it in bars. The basen also has NO off switch. I haven't used the nitecore portable charger, but my D2 only has 500 mAh output, which take over 7 hours for a 26650. Look closely at amperage, because size matters here. The one "BIG" irritation with the Golisi is that the display turns off after a few seconds so you cannot monitor your charging progress by glancing at it, you must push a button and wake up the display.UPDATE: After further use, be aware, I just bought a new Rofis with 21700 batter and it will not fit at all. The 21mm batter is too long to fit into the posts of the charger. Despite being listed in the description...mine did not fit! ### ⭐⭐⭐⭐⭐ Fast charging !!! *by S***G on Reviewed in the United States on July 6, 2018* Super fast charging. 2amps. Charges 26650 battery in 2.5hrs. ### ⭐⭐⭐⭐⭐ USB adapter included! *by D***E on Reviewed in the United States on October 31, 2018* Awesome for the workplace. If you have a single battery mod this is great to bring to work and have a battery charging at all times. It even has a USB adapter so you could plug it into your computer! --- ## 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.vn/products/56712987-intelligent-battery-charger-golisi-i1-2a-single-slot-universal-battery](https://www.desertcart.vn/products/56712987-intelligent-battery-charger-golisi-i1-2a-single-slot-universal-battery) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
