Review on ⚡ Dual Port USB Charger: Battery Tender 12V-24V, 1Amp/2.5 Amp for Efficient Charging by David Sanchez

I bought this particular USB charger because it was a Deltran product and I thought it would be of good quality like other Deltran products I have used over the years. It was "lemon". The second time I used it, I smelled smoke after turning it on and it burned out for no reason. It wasn't even plugged in to charge. It should have been an open loop. I checked the fuse, it was blown but didn't protect the circuit. Replaced fuse, still doesn't work.
