    So far it's working the way it's supposed to. It seems like the charge has slowed down to devices but it still works for emergencies

    Good, basic, high-capacity battery pack

    There's not a lot to say about most battery packs. They're basically portable chargers for your phones, tablets, Raspberry Pi, and pretty much any other mobile device you can charge off a USB cable. Anker's weird naming scheme aside, this pack has a lot of things I like about it, and a few I don't. On the plus side, the 20,000 mAH battery is quite sizable and should have enough juice to recharge most phones and tablets at least a few times. That capacity also comes with enough weight that you wouldn't want to carry it in your pocket for any length of time ( though slipping it in a bag or pack is no problem. While the USB-C port is PowerDelivery capable ( 20W max ) the regular USB-A ports can also output 12W, far more than the regular USB spec allows. So high draw phones, VR headsets, and even a Nintendo Switch shouldn't be a problem. total power output can't exceed 3A, though, so charging multiple devices at once can be slow. When charging both my phone and tablet, the tablet reached 100%, but the phone started trickle charging after 70%. The battery can also be set to a lower power output for slower charge rates. While this might be less convenient for some, faster charging also puts more wear and tear on overall battery life and expectancy. The downside of the battery is it can only be charged through the USB-C port ( in and of itself no big deal ) but it only comes with a USB-C to USB-C cable. So if you don't already have a C cable charger, or a computer with a C port, you'll need to buy a wall charger or A-to-C cable to charge the battery pack. The other drawback is the price. For this Sense model, you pay an extra $10, and so far as I can tell, that only gives you the fabric exterior. Otherwise it looks identical to the cheaper non-Sense version. Also, despite what the Best Buy product description page says, this battery pack does NOT have a magnetic or wireless charging capabilities.
