It looks like it can. 21700 wasn't a common size yet in 2015 when this item was listed so they don't say in the listing. Specs say it can take batteries up to 26mm diameter (26650) and up to 70mm long (18700). 21700 is 21mm diameter and 70mm long.

Just be aware that the output current to each cell is only 500 mA (0.5A) with this model so it will take longer to charge a cell than others that can charge at 1A-3A.

Price is good though and it should be a good quality unit.

You can save 5% on batteries and chargers with coupon code BLF in the shopping cart.

If you look at this picture, it claims to support 18700 batteries, which are the same length as 21700s.

I've been using the miiboxer c2-3000 which has two slots @ 1.5 amps each. I got it at a sale for around $14 i think. It's ok for that price. It can sometimes be a little fiddly to get the batteries to register in the charger. I think it's because slots are so large as to allow many different battery sizes
