DIY USB charger ready!

@4.8V it draws just over 2W

This is my faulty sensor tempest
Just seeing if a boost to the battery which was getting low would revive the rh sensor and others that have failed.

Should be cooked in about 1-2 hours ( from slightly above the psm 1):smirk:

Edit; about an hour and it’s almost fully charged.

The wattage halves nearing full charge.
