Power Bank, JETech 10,000mAh 2-Output Portable External Power Bank Battery Charger Pack for iPhone 6/5/4, iPad, iPod, Samsung Devices, Smart Phones, Tablet PCs (Black) – 0760

  • 10,000mAh capacity with TWO USB outputs: 5V 1A and 5V 2.1A. On/off button to stop/resume charging, 4 LED indicators displaying battery percentage and charging status. Grade A Li-ion polymer cell and premium microchips create high-quality portable charger
  • Built-in flash light. Premium aluminum case: solid aluminum alloy with anodized processing, comfortable and luxury touch;Stylish, lightweight design fits easily into any pocket or bag
  • Maximize compatibility with Android, Apple or other devices
  • Universal fits for iPhone, iPod, Samsung devices, cell phones, tablet PC
  • Package includes: JETech 10,000mAh External Battery, Micro-USB cable, instructions manual. 6-Month Warranty
  • Recharges cell phones 2.5 times when using the 1A slot (granted, I’ve only tested it on two different phones, but I doubt that would vary significantly)
    – Offers two different current options for recharging your device: 1A current (slower recharge, but more efficient so more juice per single charge of the powerbank), or 2.1A current (recharges a device quickly, but drains the powerbank. Using the 2.1A slot, you’d probably get close to 1.75 to 2 cell phone charges instead of 2.5).
    – Allows for tablet recharging for the same reason as above (has a 2.1A option)
    – The powerbank itself recharges quickly
    – Solid, quality construction
    – The flashlight is a wonderful extra
    – The price is the same as other, similar products that are of inferior construction and don’t hold nearly as much charge
