Please recommend a 10000 mAh Power Bank

8
Posted 20th Feb
I'm looking for a power bank around 10000 (or a secondary option 20000) mAh that can power 2 action cameras and can be charged quickly (i.e. Power Delivery).

I was thinking about the "Anker PowerCore 10000 PD Redux", but Anker says the power bank (and the rest of their range) will shut off after the camera batteries have charged to 100%.
I don't want that feature, I need it to continually provide power to the cameras.
(Maybe I should just remove the camera batteries).

Does anyone any experience with the above power bank (i.e. does it shut off) or can recommend one that meets the above specs?
Most of the power banks (RavPower, Aukey etc) at Amazon seem to claim this auto shut off/safety feature.

10000 mAh over 20000 is preferred due to size and weight.

Thank you

Thanks for your suggestion, but it doesn't look like it ticks any of the boxes, for what I'm looking for.
Plus it looks like a PayPal refund for a 5 Star review product.
As far as I'm aware the USB standard doesn't even communicate battery charge level (on a power-only connection).

Given that we're talking about Amazon sellers and powerbanks here, neither of which are paragons of honesty in marketing, I suspect it's an entirely spurious reassurance. The power flow shuts off because the device is no longer drawing power rather than because of anything the power bank has done.

Many thanks for the explanation

Many thanks for the explanation


As mentioned it's the device that stops drawing power when fully charged. Once there's no power draw for a bit the powerbank turns off. I've run a raspberry pi off mine and as that's a constant draw it's fine, but if doing my phone it'll turn off after my phone is done.

You can easily test it, if the cameras run off USB with no batteries then a powerbank should also run them without batteries.

I've got this one, just might take a while to come atm with corona, it has dual PD out, I got it for just under $9 in a sale.

Worth noting (it's in the description). The 10000mah is at the batteries 3.7v, it's around 6500mah at USB 5v. I'm not sure if that's an issue with all powerbanks though or if others claim capacity at 5v (I doubt it as most do what they can get away with).

Is the digital readout accurate or really just a gimmick?
