VEEKTOMX 65W Laptop Power Bank, 20000mAh Fast Charging Portable Charger Extra 100W (5ft) USB C to C Charging Cable with PD 3.0 & QC 3.0 Compatible with MacBook/iPhone/Samsung/Steam Deck/Tablet/DJI

used this for a family holiday to power the steam deck - worked great on the plane and whilst travelling.....provided around 4hrs extra (approx) game play when plugged directly into deck.....that's on top of the 3 hours (approx) i got from the deck battery, so perfect for flights and can't complain for the money...nice sturdy construction and good cables....charges mobiles in 20 minutes too....if you have a deck and need some extra juice, then i can highly recommend this battery pack

Tried a few power banks with my Steam Deck and returned all of them. This one though, fast charges the deck whilst playing intensive games and has a great battery life. Very very good, at half the price of an Anker charger and equal in performance.

Not many batteries at this price can output the 45W required by the Steam Deck, this one does with juice to spare, so it can even charge the Deck while gaming. If you connect it when the Steam Deck is fully charged, it will use this battery first before it runs its own down, so it’s good way to extend the life of the built in battery.I have used it to charge my phone and iPad, works fine, and it can handle multiple devices at the same time.Only docking one star because the capacity seems to be a bit lower than advertised. At 74Wh it should be be able to charge my 30Wh iPad twice with capacity spare, but it can’t quite manage two full charges. I guess there are some always some losses in the charging process, but an effective capacity of just under 60Wh seems a bit low. .Even so, it’s good unit, high power output, good construction, and the included cable is good quality and nice and long, and at just over 30 pounds, it’s still a good deal.

I purchased one of these to charge my S7 and steamdeck while on coaches and trains. At the same time my friend purchased one for their steamdeck.I opened the item and followed instructions about first charge etc. I was shocked to find after charging my phone from 5% to 90% only one light was showing on the battery!I decided to charge it up over night and try again. This time my phone went from 10% to 100%. I then tried charging my partners S10 and got about 10% out of it before it died. I tried charging my steamdeck (While not playing anything) and it got about 40% before it died. I was convinced I'd got a dud and asked my friend how they were getting on. They said they'd had the same problem as well but said they'd got a 50% charge out of it (While not playing anything)It seems that so many other users on here (,and on Reddit ) have had similar issues and some have even stated that it's not even close to being 20,000mAh and more like 10. While I don't know if this is factually true I can easily see how that could be true.I own an Anker 20000mah which can charge my phone 4 times easily but sadly isn't strong enough for my steamdeck.Don't buy it. Save up and buy a better brand than this if you need to charge on the move.

Everybody recommended the Anker equivalent, but at less than half the price this seemed worth a punt. My main use case was likely to be to charge my iPhone plus a Steam Deck, so 45W PD was the minimum. The extra 20W that this supplies allows me to also charge my Asus G14 laptop.One think I really like is that it starts to output as soon as I plug device into it. The previous power banks I owned required me to press a button.If there was a Qi option for maybe £20 extra then I would have gone for it, but for the asking price without Qi I can’t complain.

I use this device to double the battery life of my Surface pro 7. Power Delivery is excellent.It is a robust device and have relied on it several times.It cannot be beaten for price; it is more than 50% cheaper than comparable laptop charging banks.The device is the same size as a iphone 14 pro max that has double the thickness.Overall a must buy if you are worried about finding a mains outlet when you need one.

Fully charged this power bank, can keep a fully charged steam deck going (at its TDP) for about 3h 15min, at which point the battery is empty and the deck starts discharging on internal battery.I measured 48.5Wh @ 15V (PD PPS) vs its cells rated 74Wh which is a lower efficiency (~65%) than I had hoped for (65% is on the poor side of modern power banks), I guess the efficiency will be better at 5V, but have not tested that as I wouldn't be buying a high wattage power bank if I just needed 5 or 10w charging.However, it delivers all the wattage needed, It stays cool, and it seems well built.If the price is right (Aim to pay £25 at 30 there are better options that clearly came from the same factory with higher capacity).. It is an ok option for the Steam Deck.

These PD bricks are very useful if you travel with a laptop, it will run most laptops very well as long as you have the right USB-C adaptor.The only drawback is that it uses the same USB C port for recharging and is you have power coming into one USC-C socket you can't draw power from the other. That seems to be a common issue with similar bricks, I guess it's a cost issue.
