The Firefly 20w was able to charge my wife's BPS C-100 CPAP 12v back-up battery. Charging the CPAP back-up battery took the Firefly from 100% charged down to 47%. The Firefly's pure-sine wave inverter is safe for electronics, and the solar rechargeable Firefly means we are good to go for extended camping where outlets are not available. We also feel a little more prepared if the power ever goes out for more than a couple of days after a hurricane.
We added the Renogy 50w poly
Renogy 50 Watts 12 Volts Polycrystalline Solar Panel
for quicker solar charging time. The panel was ready to hook up to the Firefly, straight out of the box, with all connectors included and no need to purchase anything else.
The Firefly's all-in-one design takes the guesswork out of solar back-up for CPAPs for the electronically challenged. Highly recommended.
