• A 10000MAH BATTERY SMALL ENOUGH FOR YOUR POCKET; This is a mini power bank that packs 10000mAh of power into a compact body measuring 4.48 by 2.81 by 0.67 inches and weighing only 5.76 ounces. It fits in your pocket, purse, wallet, or the smallest compartment of your backpack. You get a full day of phone charges without the bulk of a standard power bank.
• STOP CARRYING BULKY POWER BANKS THAT WEIGH YOU DOWN; Most 10000mAh power banks are thick, heavy bricks that take up half your bag and add unnecessary weight. You end up leaving them at home because they are too inconvenient to carry. This mini charger fixes that problem with a compact lithium polymer design that delivers the same capacity in a body roughly the size of a credit card.
• CHARGE IPHONE UP TO 2X, SAMSUNG GALAXY UP TO 1.5X; The 10000mAh capacity delivers enough power to charge compatible iPhone devices up to two times or Samsung Galaxy devices up to 1.5 times before the power bank needs recharging. Recharge the unit in 4-5 hours via USB-C or Micro-USB input. Standard 5V/2.4A output provides reliable charging performance for everyday use.
• BUILT FOR TRAVEL, COMMUTES, AND EVERYDAY CARRY; This is for anyone who needs backup power without adding bulk to their daily load. It fits your routine if you commute by train or bus and want a charger that fits in your pocket, travel frequently and need TSA-friendly carry-on power, or spend weekends camping and want reliable backup that does not weigh down your pack.
• TSA-FRIENDLY. DURABLE. BUILT TO LAST; At 0.67 inches thick and 5.76 ounces, this is one of the most compact 10000mAh power banks available. The durable ABS shell helps protect against everyday wear and impact. Built-in chips help prevent over-current, over-voltage, overcharging, and short circuits. FCC and CE certified.
