Those "number of full charges" figures are assuming 100% efficiency, which doesn't exist in this world. When charging a battery, you're lucky if you get 70% of the input energy back.

Note that while practically every phone or mobile device has a USB connector or for charging and data transfer, not all such devices will actually CHARGE when connected to a 5-volt power source such as this. Many plug-in chargers deliver more than 5v to their devices. That's why specific compatible devices are listed along with other devices "with 5V input". If your device actually charges, not just lights up, when connected to a computer's USB port, it should charge from this battery. If your plug-in charger delivers more than 5v to your device, this battery might still charge it more slowly, or not at all.

Just bought two. FYI it has TWO USB inputs to charge two devices simultaneously.

This would be so worthwhile if spending a length of time in the back-country. So many phones take great pictures & videos, but can really drain your battery, too.
