(The solar function is specially designed for emergencies，it\`s not a primary source of      charging due to the compact solar panel size， it charges slowly and ensure that the 
powerbank has some power before you charge it by solar. In general usage， we recommend      charge the solar power bank by cable to shorten the charge time.)
 
 Note
Though we only supply  USB Cable ， but you can charge any machine with this battery with      your own USB charge cable !!
 
How to use
1. Usually there is internal resistance in all mobile. and power bank will lost power when      you charge mobile because this internal resistance.  we called it is Conversion Rate
2. About 5 to 6 hours charge can get the power bank full of power in normal times
3. charging time depending on charger.the more，the faster
4. the output power is different for every mobile. because mobile internal resistance is      different. 
5. All the power bank has Conversion Rate，as well as your phone，Charge will happens twice      energy conversion!
6.The conversion rate may be 45%-60%，As a result we will fell the real capacity lower than      the Rate Capaity，This kind of phenomenon is quite normal.
