72V (20S) to 5V switching power supply?

kingjamez · Apr 16, 2017

I need a 5V power supply to power 2 USB ports on my ebike. I'm using a 20S lipo pack and am having a hard time finding a voltage regulator that can handle that high of a voltage. Any suggestions on a unit than can take in up to 84V and put out 3+ amps at 5V.

I'd even take one that put out 12V since 12-> 5V converters are easy to find.

Many ac/dc wall wart style phone chargers work fine on higher dc voltages. Have you considered those?

No, but I'll give that a shot. Good idea.

Well that worked. The first Wall->USB adapter that I tried just worked. That was easy. Thanks!
