Dual port usb solar energy power bank charger for smartphoneSolar charger is converted into electric energy through the photoelectric conversion device of solar energy power banks, solar charger principle is: the lithium battery energy into electrical energy and stored in the built-in capacity through the photoelectric conversion plate, and then through the control circuit of the built-in lithium battery electric energy charging through gas export to mobile phone, digital camera, MP3, MP4 and other digital products, the solar energy power bank charger in the long-term without sunlight, can also through the city electric (AC100V-240V) charge, to the built-in lithium battery, standby power supply suitable for travel, tourism, travel, field operation environment of ship. 
Combo charging lighting with LED lighting technology, mobile solar energy power banks can also become nocturnal flashlight, convenient and practical. As long as there is sun, sun sun can recharge, outdoor charging artifacts, emergency, rescue, survival kit.
Aviation aluminum, grinding process. Using aerospace aluminum alloy, matte design for the customized solar power banks, feel better, with compression, wear-resistant, non-slip characteristics.
It is Dual USB for the solar energy power bank while the fast charge, two USB output port can charge two devices at the same time, the rapid electric storage support powerful tablet and mobile phone simultaneously charging.
Specification of Solar energy Power banksWeight: 305gInput: 5V 1A/2AOutput: 5V 2.1A maxCharged by electricity: 5 hoursCharged by Solar: ≥40 hours
