Just a guess, but it might be the higher voltage..  Just because the Anker can put out 2.4A, does not mean the camera draws that much current.  Current drawn is the voltage across the circuit divided by the impedance (resistance) of the circuit.  So if the impedance is the same for two voltages, the higher voltage will result in a higher current.

If this is the case, then they can't speed up the charge time using USB, since that must maintain the standard of 5V or risk damaging  "other" devices.  I'm surprised they dare put 6V on the USB plug from the solar panel (unless there is another power port I've not found yet).

Hi folks,

By "3 hours", we mean that's how much sunlight the camera needs every day to top up its battery and stay powered. Whereas the "5 hours" is how long it takes the USB interface to charge the battery from zero to 100%.

So if you're setting up for the first time, we still recommend that you fully charge to 100%, even if you had the Solar Panel.

This is a completely meaningless statement by itself. I'm not trying to be rude, just logical. You can't possibly make that claim without knowing how much sunlight the panel is getting, whether the battery is at 40% or 90%, etc.

How did y'all come up with that estimate?
