… back to the initial thread i.e. “fast charge powerbanks?” I think that the new “key point” in fast charging might be represented by the emerging USB-Type C connection.
As far as I understand Type C is not a new USB: USB-Type C can encompass indeed already existing USB well consolidated standards such as 2.0-3.0-3.1_Gen/Gen2-PD_Power Delivery and so on so forth.
It seems so far that the “C” refers exclusively to the connector type that is
- very ROBUST whether compared to existing mini-micro type A, B, etc.
- totally REVERSIBLE, i.e. pluggable upside down with no orientation distinction
- suitable to DUAL ROLE function, capable in other words of automatically recognize and adapt voltage&current within the Power Delivery USB specs, either in the role of supplying or being supplied device.
Searching on the web it appears that either Anker and Rav already offer such new USB-Type C/PD Power Packs that, mAh/Wh apart, exhibit considerable improvements into the direction of “fast charging”.

There's my nasal hair trimmer, travel electric toothbrush, battery operated nail clipper. I share the battery between all three, of course - gotta travel light and rough it sometimes :D

USB power pack that *recharges itself* quickly?

Does anyone know of a USB power pack that recharges itself from a mains socket particularly quickly? Most 'fast charging' features relate to the speed with which a device is charged by the power pack, not the speed at which the power pack can recharge.

My typical usage for a USB power pack while cycle touring is that I top it up while stopping for lunch or in a cafe, and then use it to charge up any devices (camera batteries, phone, GPS) while riding or in the tent overnight. So the faster the power pack can recharge the better.

I recently bought a Motorola G6 Plus mobile phone that has an fast charge function. Using the dedicated 15W charger, the phone charges can get a complete charge in an hour or so, which is much faster than my previous mobile recharged.

thanks in advance for any suggestions

I have a 26800mAh Anker Powercore that has dual 2A inputs (20W).
