• 8000mAh lithium polymer battery
• Waterproof and dustproof
• Drop-resistance
• LED flashlight (double click power button)
• LCD charge indicator
• Solar charging: 5V /200mA
• Input: DC 5V/1A
• Output: DC 5V/1A
• Dimension: 13.7×7.4×1.6cm

• SB6286 High Efficiency 1.2MHz 2A Step Up Converter.
• 4056 Linear Li-Ion Charger.
• DW01 One Cell Lithium-ion/Polymer Battery Protection IC.
• 20pin SMD integrated circuit with no label, probably a microcontroller
• 107mm * 61mm * 3mm Solar Panel, probably 5V, 170mA

• The case would be water resistant, but would not survive being immersed in water, it is not water proof.
• The battery in my sample is rated at 4000mAh, not 8000mAh as stated (and printed on the case).
• The solar cell is not really a practical way of charging the battery. In the best conditions, with 100% efficiency it will take 40 hours to charge a 8000mAh battery. So under the best condition, with 8 hours of strong sunshine a day, it would take 5 days to charge. Perhaps if you were marooned on a desert island near the equator, it would be useful, … if there was also cellphone coverage there …
