T E C H N I C A L F A Q
Can the 20K charge my device while it's charging? YES, but only at the rate of input (aka normal rate when charging via AC, slower rate when charging via solar only)
Can the 20K charge more than just my phone? YES - tablets, go pro, you name it.
How long does it take to charge the 20K via the solar panel? 58 Hours to a FULL charge (variable based on directness of sunlight), and only 4-6 hours for enough power to re-charge your mobile. This means if you rely strictly on solar, you could charge the battery during the day, and have plenty of battery to charge your mobile at night.
About how long would it take to charge my mobile phone? Around 0.5-2 hours, depending on the capacity of your mobile device.
If I leave my battery fully charged, but don't use it, how fast will it lose charge? In roughly 2-3 months, if left totally unused, the battery will lose 20% of its stored power.
Can the SOS20K produce output while it's being charged? aka charge other devices while simultaneously being charged? YES, but only at the rate of input (aka 340mAh from solar and 1A from wall charging).
Can I take the SOS20K on an Airplane? According to TSA regulations, all passengers CAN carry external batteries with a maximum capacity of 100W hours (20K mAh @ 5v) with them in their carry on. The TSA asks that these devices are NOT placed in checked luggage, so as to be easily accessed in the rare case that a battery malfunctions.
