I purchased this Lumsing 8000mAh Ultrathin External battery pack to take on a trip. It is a very lightweight, ultra thin and will fully charge your device at least one full time. This high capacity, 8000mAh battery pack is ultra slim, the thickness of this device is only 0.35 inches and the dimensions of this device are: 5.1 in x 0.4 in x 2.8 in and weighs 5.9 ounces. Inside of the box you will find:
1.- Lumsing 8000 mAh Power Bank
1.- Micro USB Charging Cable
1.- User Manual
1.- Lumsing User Card
With the size of this power bank, and the capacity it is easy to take with you on a trip. You can easily put this device in your pocket, backpack, purse, briefcase, or bag and take it with you on your trip wherever you maybe going no matter if it is by car, train, bus or plane. Just having this power bank with you, you will be able to recharge your phone 2 times (depending on model and type).You can recharge this power bank over 500 times, it takes approximately 4 hours to recharge this power bank from a zero charge. Mine came fully charged, it has LED lights to let you know what your current charge is. If 2 LEDS are lit then it is fully charged. If you have one blue LED then you have 50%-100% charged. I would have preferred more warning between halfway charged and empty(zero charge), or full charge. If you don’t keep up with the last time you recharged your powerbank, you could find yourself running out of power when you need it most.
This power bank also comes with a flashlight, to operate it you simply press the power button twice. It will light up your whole area. To turn it off, just press the power button once again. This wonderful product from Lumsing is covered by a full 12-month warranty, if you have any questions or problems with any of your devices from Lumsing then you need to contact them and let them know so they can help you.
