DollaTek 600W DC 10-60V To 12-80V Step-up Module Boost Power Suppy DC Converter

Does exactly as I wanted. Have a 24 managed li-po bms battery pack I use to run lights and charge power tools via 24v inverter in the van.Made a power box with this boost converter set to 28v at 5 amps and then a cigarette light plug on the input and it charges battery and it works perfectly. Additionally a temp driven fan to cool the box and all good.

works perfectly. i used a multimeter to monitor the output, once i applied 12v to the input, set my output voltage and current and it just works. nice touch having 5.5mm input and 2x screw clamp fittings as inputs.

The stated voltage range is misleading - this will not reduce voltage, despite the output being described as ‘adjustable’. Shame, because it seemed like a good unit.

Good product but would benefit from screen that shows voltage output and current output. Used to lift 12v to 53v to charge 13s4p lithium 18650 pack.

I brought this with the idea to feed my solar panels through to up the volt so that I can charge my electric bike when I go out on it giving me more range to travel this is working great at the moment as we have nice weather will have to see how it goes in the winter.

It's great using it to charge high voltage battery packs and now integrated into laptop power bank

Used it to step up 12v - 58.8v for a LiPo charger. Works well and provides stable voltage. I recommend using a fan.

defective item - sparking from output terminals and smell of electrical burning when tested with multimeter
