I hope they do! I had ordered quite a few products from them a while back. I have been using the (2) SV2’s to charge (4) 18650’s for my GT’s. I can rig up something to make it work, but I shouldn’t have to, if this is a manufacturer defect! I did try calling them a few minutes ago, but they may be out for holidays or something. I’ll post back when I do get in touch with them. Thanks!
