56W Power Adapter Fast Charger Compatible with NOCO GB70 GB150 GB250+ GB251+ GB500 GB500+ Genius Boost Ultra Safe Lithium Jump Starter Battery,14V 4A AC/DC Adapter XGC XGC4 Output Battery Charger

Works as described and feels decent light weight also

works good

Works great and compact enough to fit into the Noco battery case.

Fit my jump box and charged it fast

I recently reviewed a similar power supply (ASIN B0CYC4TYYV) which was little smaller than this - but lacked the indicator light this unit has. I wish someone would make a unit the size of the other one with this one's indicator light. I didn't have a chance to completely drain and recharge my GB70 but will update these reviews if any issues arise doing a full charge. The included cord plugs directly into the Noco and the Noco's charging indication comes on as soon as the brick is plugged in. The brick's green indicator light comes on whenever the brick is plugged into wall power. Given today's technology the unit actually seems a bit large for the rated 56W power, but as above I'll need to try a full cycle on the GB70 to see if either tested unit overheats or anything - and I'll update the reviews if any negatives arise. It's certainly possible this unit's larger size is for better heat dissipation, but I honestly don't think so - it's too light for there to be any substantial metal heat sinks inside.

Works , charges my NOCO GB 70 much quicker than any other method !!

Exactly what was needed.

I have the GB70 and the jump start actually died while being plugged up. The charger does not work at all.
