Dumb Question - Can I use a USB Charger from a 6v battery.

[stealthmayhem]

Quick Background.....I have a travel solar panel that puts out 9 volts @ 1Amp. I use this to charge a 6v Deep Cycle marine battery. Could I just hook up my USB charger to charge my 18650 batts or would it burn out the charger? Or should I hook it up directly to the Solar panel? Any help would be appreciated.

Can you provide some info on the solar panel, maybe a product link somewhere we can see the specs on it?

USB is supposed to supply 5V, with a tolerance of 0.25V in either direction. Fully charged, your "6V" battery is probably close to 6.5V. That's way out of spec for USB. Will this kill you charger? Depends what chip is in it. Some have maximum input voltage ratings as low as 5.5V, while others are much higher.

Travel solar panels are used all over the world by woodsman and explorers who are operating way out in the back of beyond. They are used to charge cellphones, GPS systems, video cameras etc. It should have a USB charging port and will charge a vaping device no problem..
