With PowerIQ and VoltageBoost technology, it\u2019s capable of quick charging (except Qualcomm Quick Charge).\r\nDesign\r\nWhere its performance outshines many other portable chargers, the Anker PowerCore 20100mAh falls short on its design, specifically its dimensions. It is by no means a lightweight external battery; this is a beefy charger as far as power banks go. While it isn\u2019t as wide as the INIU Portable Charger 10000mAh or Portable Charger Power Bank 24800mAh, it\u2019s much longer. So long in length and so weighty that you\u2019ll notice it in your pocket. In fact, it\u2019s 12.5 ounces.

That\u2019s especially helpful if you and a friend both need a quick charge. It also helps that the portable power bank has a solid build, too. It\u2019s definitely a sturdy device that will certainly survive a few accidents. To sweeten the deal, a micro USB cable is included, but not a lighting cable, sadly.\r\nAnker PowerCore 20100mAh Wrap Up\r\nThe Anker PowerScore 20100mAh offers one of the best options for steering away from wall chargers.
