Any way I can safely charge an Efest 18350 in a standard 18650 charger?
I swear by Nitecore Digichargers. Also, avoid LUC chargers. They're by Efest. Wouldn't trust Efest to make flashlight batteries, much less chargers or vaporizer batteries.
You got suckered by the seller.. I knew about the USB port thing and that it was only for Li-Ion before buying by simply looking it up on the site..I have a brand new LUC V4 that works like it should in one way. That's to charge the batteries to what I can tell using a Fluke meter pretty accurately but I despise the charger and the people who sold it to me. It was advertised as a universal charger having an included USB port. Sounds perfect for us that still have an EGO or two laying around. By accident I contacted another vendor on Amazon where I got my charger from that also advertised there LUC V4 the same way. Here lies my problem. First it is only a lithium charger and will not charge Ni-Mh batteries like the Nitecore will. The USB port only works if you put a battery in Port 2 of the charger with the charger unplugged basically turning it into an 18650 powered USB charger. If it is plugged in with a USB cord attached, port 2 will not charge a battery. The other person I spoke to wasn't even aware of that.(tells me there trying to hide it until its to late) To claim having a USB port on a charger anyone would assume it is used for charging in addition to charging batteries since they went as far as saying it has a 500mah rating. Its nothing more than a pathetic ploy to sucker buyers to there product instead of an actual well designed and built charger with out gimmicks. Mine is a month old. When I get the money to replace it I will burn it and post it with the explanation of why it is burning. I would love to keep everyone I can from buying something under such pathetic and false pretenses. If I could figure out how, I would get the video and this post to the people who make it.
Stepping off of my soapbox for now.
