BESTEK 4.2A Dual USB Car Adapter and 110V AC Car Inverter 300W to Power Inverter DC 12V Power Converter Red

Living in the middle of nowhere, I use battery powered lights from DeWalt for the time being, use this to plug in the charger during my drives to town. Worked flawlessly for weeks, but now it eats fuses. I swap a new one, charge starts up, but I suspect the adapter took a knock somewhere along the way jarring something loose which I may have to insulate/re solder, there's obviously a short in the unit somewhere now. Glad Amazon carries 10amp mini fuses by 60 for less than 4 out of Canadian tire. Good unit, useful and does the intended job, but treat it gently. *UPDATE* I was wrong,this unit works flawlessly,I now believe the issue was caused by a DeWalt battery charger. I am not an electrical engineer, but suspect that at times the battery in charger sends juice back to the outlet which sends that back to the car system and blows fuses. Not certain, but makes the most sense to a layman like myself. Running a 120w charger for my necessities has no issues with fuses at all. I would think this unit would have some protection for such behavior,but then again, I would rather pop the hood to swap a fuse than disassemble this unit. This unit does exactly what is promised, and I do apologize for any confusion I may have caused. Sturdy unit, would buy again.

Its an inverter - it does what it should. i can run my work laptop and charge phones in my work car

Exactly what I was looking for, works well. I chopped the wire and added an inline fuse to it so if the fuze was to blow it would blow the one I attached to it instead of the cigarette lighter. Since it takes 28.5 Amps to run I added a 30 Amp fuze.
