XTARSN4 11 in 1 Camera Battery Charger for NP-W126/W126S Battery Support Fujifilm Camera to Fast Charge with 3A Maximum Current(SN4+2*W126S Plate)

Really pleased with this charger, now I can charge all my genuine Nikon batteries including the EN-EL15C batteries which as Z users know can be really picky on the charger used. Also came with a USB C cable, bag and a cap for when only using the dual charger.

thought this would be a good buy and save time charging multiple batteries but just flashes and doesn't charge despite changing cable and charging plugs.

I first remember seeing this product on one of those funding sites and thought it was a great idea. The ability to mix different batteries and/or be able to charge 4x Sony FZ100 batteries for me was a great idea!My wife & I have a photography/videography business so when charging up we use a lot of chargers. So having one charger that can charge 4 batteries would be fantastic!The first problem I had was that one of the ports (the third from the left) refused to charge any Sony battery I inserted. I tried reseating the battery plate but to no avail. I was about to return it when I suddenly thought "What if I swap the plates around?" Bizzarely that worked and now it charges all four. Great I thought! Problem solved.Except one problem which I think is very poor and unforgivable.None of my batteries charge to 100%. Despite using a 65w USB-C PD compatible power adapter, leaving the batteries to charge overnight and all the lights being 'full'. When I put the batteries into the camera, they only report 95%.Before anyone asks, these are all genuine Sony NP-FZ100 batteries and charge to 100% with no problems using our other third party chargers and of course the genuine BC-QZ1 charger.I'll keep it since it wasn't expensive and I've thrown the box out now. It'll still come in handy to charge batteries most of the way when we've a busy wedding day ahead. But it's just annoying that it can't charge to 100%

Lights flash, batteries stay uncharged
