Hey peoples. I've stumbled upon this fAst charger for my insta360 X4 batteries. This charger isn't self powered as you need a battery of some sort of powered connection in order to view information via display. this thing is very nice. It's relatively compact, will hold your batteries as a storage box and tells you how healthy your batteries are. Cynova is a company that makes official parts for insta360 so I had no qualms about making this purchase.
Always remember to NOT charge hot batteries. if you are rotating batteries make sure the battery you just used (which may still be warm) cools off a bit before charging. This is a non-sponsored video but you could easily find this item on Cynova 's website or on Amazon/eBay.
