We suggest you consider Gyrfalcon All-88 Battery Charger as an alternative.

Efest Blu6 - Bluetooth technology for your lithium ion battery charger!

It has 6 bays so you can charge tons of batteries at a time, and you can charge them fast with up to a 2A charging rate (selectable).  An LCD screen will give you basic status or you can pair the charger to your phone (Android or iOS) to get updates while you're away from it!  This charger is very much in demand right now.

It's compatible with most 3.7V Lithium Ion or Li-Mn batteries such as 10440, 14500, 14650, 18500, 17670, 18650, 18700, 26500, 26650* (see note regarding Aspire/IJoy), 20700**, 21700** (including the iJoy 20700/21700) etc.  

It can also charge 15270 or 14250 batteries if you use spacers.

Battery Specific Notes:

*Note that due to the width of 26650s, this can only charge 3 of them at a time. Also, we do not recommend this charger for the Aspire or IJoy 26650s, as their narrow tops don't fit very securely and could easily come loose!

**This is our favorite charger with respect to 20700/21700 batteries and their size since it leaves a little room for them at the top.

We DO NOT offer tech support and troubleshooting if you have issues with the Bluetooth aspect of this charger. Bluetooth can be very finicky, and we're not the best equipped to help you if you're having that issue. If you are having issues with the Bluetooth, we suggest you contact Efest ( for assistance. Thank you for your understanding.

Great charger but OLED screen failed

I have been using the OLED version of this charger and it has worked great up until the last month or so when the backlighting on half the OLED screen failed. I wish I would have waited for the LCD version. I would still recommend this charger nothing else matches its capacity and flexibility.
