SIWIQU 20000mAh Power Bank for Steam Deck, 45W PD 3.0 Fast Charging Battery Bank, External Battery Pack Compatible with Steam Deck with Detachable Back Mount & Dual USB-C Cable

Works great, exactly as it should. I personally find it way more convenient than the regular charger. It’s quite heavy, but that’s to be expected from a battery that size. Holds charge well, and from full battery I’ve managed to fully charge a steam deck twice while actively playing it. Fits nicely onto the back of the console. I’ve only used it on a steam deck, so can’t speak for any other devices, but it’s done for me exactly what I needed it to

After using various portable chargers for his Asus Rog Ally, my partner needed something that would give him more than what he currently has. Anyone who owns a handheld gaming console (especially high powered ones such as the Rog / steam deck) know that the power consumption is high and having it plugged into the mains seems to be the only logical way to keep playing for more than a couple of hours. I came across this, which actually has a clip to hold it on the steam deck, to see how it would fair with the ally.This thing is a beast compared to what he has been using. The 20,000mah battery has charged his device 2.5 times already from 18% and 20% respectively and it has only just used half the power banks juice. This is without adjusting the settings to power saving mode or anything.It is a bit bigger than other ones you can get, but that doesn't make a difference to the performance of the charger.I would highly recommend this to anyone who is after something like this!

The only power bank that I’ve found that charges a steam deck without breaking the bank. It charges as you play which is great. It also doesn’t get too hot if you’re playing and charging simultaneously. Clipping the power bank to the deck does add a significant amount of weight but you quickly get used to it. I’d recommend.

I bought this product in Feb 2024. It seemed great at first but after several months the product is now faulty. The powerbank is dying after charging my Samsung S21 Ultra. Have tried tablets etc and the powerbank just isn't holding charge anymore. Returning this product is also impossible as it has passed the return window. Be careful what you buy from Amazon.

Works as described also will still fit in the steam deck case with it(mount not battery). Only problem is it is a bit heavy with the battery slotted on

So when I opened the box I felt it was slightly lack luster, however once I actually used it I was surprised! So it is heavy, I did think it was too heavy to impact the way you hold the steam deck. I used this while playing fallout 4 full spec and it doubled the life of my steam deck play time. It actually charged quicker than the power was being drained which is impressive. Good value for money, ease of use and quality are all 5 stars. A must have for lone flights or commutes.

The media could not be loaded. This is a brilliant charger which has a fantastic amount of battery life. Useful for charging all kinds of devices, I’ve used it whilst gaming handheld, for my phone, kindle, camera, you name it! It charges quickly and doesn’t overheat like some other devices I’ve tried previously do. Much easier to carry one large capacity power bank than multiple smaller ones, so very happy with this! Would definitely recommend.

I don’t think I’d be able to play my steamdeck with this clipped to the back. It does make it a little heavy. But I play mine in bed. If you had something to rest against it’ll be fine. Other than that. The thing charges my phone like mad. It charges the steamdeck really well also. Seems to hold quite a lot of charge aswel
