  • Review: Flash 2.0 USB-C Graphene 210W Power Bank is powerful but costly

    Compared to a typical 20,000 mAh battery pack, the Flash 2.0 is larger (18.24 cubic inches vs. 14.26 cubic inches), heavier (17oz vs 14oz), and about four times more expensive.  It seems that the other claim to fame for this battery pack is charge/discharge speed, since my USB-C battery pack of similar capacity won't charge in an hour .  It also appears that the graphene batteries are supposed to support more charge/discharge cycles than traditional lithium ion/lithium polymer batteries, though it's painfully difficult to get a straight answer on such things.
