Portable Charger RAVPower 20000mAh USB Power Banks with Dual iSmart 2.0 USB Ports, 3.4A Max Output, 2.4A Input £16.69 Prime / £20.68 Non-Prime Sold by Sunvalleytek-UK and Fulfilled by Amazon

Have a very similar RAVPower and have always been very happy with it. This looks to be an excellent deal.

Great deal OP! For non prime members that have USB C devices and want to get 3A charging/recharging speeds, this might be worth considering for £26 after discount:

Excellent price! Top brand. Heat

OP change the headline

I'm not a prime member and just bought this for £16.69. Just remember to add the discount from the drop-down menu where it says 'Promotion message' and crucially change your delivery to the free 3-5 days option.

Brought this for the same price last year, well worth it, going great, no issues. Capacity I am finding is about 18,000mAh not 20,000 but seems better than anker in this regard

Good price!! I need a powerbank with 3A Output to quick charge

I thought 3A/5V was proprietary I.e. Qualcomm QuickCharge and MediaTek PumpExpress? Will this charge these devices at full speed?

No, it is 2.4A per port max, but I'd guess most devices won't be able to take more than 2A. It does not support any of the newer quick charging technologies. If you want that you have to pay £9 more (see my link above)

I have a 20000mAh pack for travelling. I wouldn't travel without it

This will charge at 80% of QuickCharge and USB-C speeds (2.4A vs 3.0A). I own this powerbank (amongst others) and it will happily charge my wife's iPad and my own S8 at full 2.4A's (Indivually) or 2.4A plus 1.0A with both ports occupied.

The powerbank is well-built and I have used it daily for ~4 months without issue. The powerbank itself takes around 9 hours to fully charge from a 2.4A wall socket, or Samsung / Apple fast chargers.

Note that this bank really does provide 20,000mAh capacity, and that it holds almost as much charge as RavPower's 26,800mAh version which yields closer to 22,000mAh. I have both, plus a USB power analyser.

This is the best value for money powerbank I have owned/tested.

Does this support pass through charging? Looking to supplement a dash cam for supermarket car parks etc

Excellent power bank 🏾 and pretty quick charging too in my experience

What is the better deal? This, or the Aukey 20,000mAh posted on this site a few days ago (android user)? Cheers.

Couldn't say no for the price. ty op!

Any good for the nintendo switch??

it may deliver 80% of the current but proper quick charge doesn't just operate at 5V so its not really the same

Great powerbank, I’ve had mine over a year with no issues. They come with a lifetime warranty believe it or not...

Hot. Minimal fake reviews.

Hmmm, can't see the promotional price on the drop-down. Perhaps the offer has expired?

The only promo code now is for £3.30 off.

Expired.
