Too much voltage for dc USB boosting converter ? Answered

I have a 6v rated solar panel but am also using 3 rechargeable aa batteries, 3.6 volts. My USB boosting converter is rated for 3v-5v input and obviously outputs 5v. Would the 6v solar panel damage the boosting converter if it were to output 6v?

It might not damage IT, but it may well pass through 6V to damage the load.

That said, your panel's "6V" rating is likely to be open-circuit condition, and not into a load. Measure the panel output at full sun, into your converter, but put a 4.7 Ohm load resistor on instead of anything breakable, and come back to us.
