Alright folks, got my powerbank today and it works fine. Here are the details:
Power Bank:
RAVPower 26800mAh
USB Cable:
Anker PowerLine USB-C to USB-C 2.0 Cable
Test details:
I played Zelda on my switch in portable mode and ran the battery down to about 50%. I then plugged it into the power bank using the specified cable, and the Switch began to charge
whilst I continued to play Zelda.
Now, as for the negatives:
- When I plugged the charger in, the Switch did not give me any indication that the unit was charging. This may have just been a quirk/glitch.
- It charges relatively slowly. About 1% every 3-4 minutes whilst continuing to play Zelda.
- The wall-charger that comes with the Powerbank has been listed by multiple sources are being a bit dodgy. To be explicit, the Power Bank is fine but the wall charger should not be used.
- The Powerbank is FUCKING HEAVY. It's probably about the same weight as the switch itself. This is no issue if you have a bag with you, but if you were thinking of carrying it in your pocket that might not be feasible.
- The Powerbank does not come with a USB C cable. I had to buy one separately. (It does however come with a C-Type adapter, but this obviously won't have the Power Delivery capibility)
That said, the capacity of this thing is huuuuuuge. 26800ma at even a 70% efficiency is still more than 4 times the capacity of the switch itself. If you're going on a long journey this thing is going to keep you going for a hell of a long time. I'm pretty content with it.
I haven't tested any of its USB 2.0 ports using my A-C cable because there hasn't been enough time. If anyone is interested I can do that tomorrow.
Anyway, hope this helps and if anyone has any questions feel free to shout and I'll do some more tests/try stuff out for you.
