I'm not sure that the cord on this thing is robust enough (stay connected) to trek around with a GPS or electronic gadget in hand. It probably works best charging an unpowered device stashed in the backpack. A dynamo charger might be more effective and quicker.

Then you're all set for the zombie apocalypse with that standard battery then. This is for when a standard battery doesn't work.
Is it best to charge a portable battery with this versus phone directly?

If possible, charge the device directly.
If you are in low-light situations, you may be better charging the portable charger however - especially if the light is too weak to provide 10W power, and you have a high-drain device that will drain power while it charges.

Slider said: Is it best to charge a portable battery with this versus phone directly? No charger is 100% efficient so charging a portable battery will lose some power, and then using that battery to charge the device will lose some more power. Charging the device directly will cut one of those charging inefficiencies. There are some instances when charging a portable battery will make more sense. If the portable battery can fully recharge your device multiple times, and you will be in direct sunlight for some time, it might be best to charge the portable battery.
