Solar charger

[riba88]

I bought solar charger with internal batery. On back side says that it has 5,5V output. My charger that i get it with phone has 5V output. Can i damage the batery if i use that solar charger?

If the output numbers match up (or are lower than the receiving end), then you should be fine.

USB (2.0) standard is up to 5.25V max.
but you might have a look at your phone's specs ... old Nokia phones did tolerate 5.5V max.

Spoiler

... BTW, I don't recommend solar chargers with build-in battery !
Charging the phone with such a solar charger is not the problem

But charging the the build-in battery of the solar charger by using the sunshine, that is a problem
It works, but, with a reasonably build-in battery, its panel needs about three sunny days to charge its build-in battery.

The reason for this delay is a general design error of this kind of solar chargers with build-in batteries.
The panel needs the sun, but the in-build Li-Ion battery hates the heat of the sun.

A Li-Ion battery to charge above temperatures of +45C (+113F) will be dangerous, so the charging circuit will shut off the charging when the battery reaches this temperature.
So there will be delays, because when the sun is the brightest the charging of the solar charger will be shut off

Far better are solar panels without a build-in battery. They can charge the phone directly or can charge a separate mobile charger's build-in battery for later use.

For such a "stand-alone" solar panel one should choose high quality.
Cheap panels won't become a joyfully toy
