To go all in on Type C sounds idyllic, but as I found with an AUKEY pocket power bank, it can cause more problems than it solves. The right compromise in this day and age is to have both USB A (i.e. standard USB) and Type C outputs, so you're covered either way, and then have Type C as the input, for refilling the power bank. And that's what this BlitzWolf accessory delivers.
In fact, it goes further rather cleverly, in that the box includes a microUSB-to-Type C adapter, meaning that if you do use this cable and are stuck somewhere that's Type C-unfriendly then you can use any old microUSB charger to put in the relevant milliAmp hours. Well, as long as you don't lose the adapter, anyway. [It also comes with a bog standard USB-A-to-microUSB lead, the idea being to use the adapter to make this a USB-A-to-C lead, but it also means that you can use this cable to charge older - spit - devices too. Just saying...!]
But that's a side issue - the thing to highlight here is the dual USB A and C outputs. The BlitzWolf 6700mAh power bank is all black and all metal, which is how I like my accessories, with the status LEDs mounted in the button to activate them, which is a nice touch, and with the power bank's vital stats printed at the other end, as shown.
However, USB Type C charging usually involves either Quick Charge 2.0/3.0 (e.g. on the Elite x3 in the Windows world) or 'Power Delivery', i.e. high current at 5V, so 3A typically and 4A for some Android phones. The BlitzWolf accessory here supports neither, though in fairness each output does go up to 2.4A, so we're not far off the 'maximum' and this is a pocket solution that's trying to keep the weight down. Or as far as possible, given that there are two Li-Ion batteries inside!
Although the current maximums are a little disappointing, it's still cool to have over 24Wh in your pocket in a gadget that plays nicely with your other USB Type C gadgetry.
The £18 price is a little high, for the size and capacity, but then again, the metal construction and Type C-centric design aren't that common still. Well worth considering.
