SiWiQU Portable Power Bank Compatible with Steam Deck, 20000mAh Detachable External Battery Pack 45W Fast Charging for Steam Deck, MacBook, iPad, Dell, HP, Notebook, Samsung, iPhone, Switch and More

Got this for my partner for his steam deck. The steam deck alone can fun out of battery very fast. This has really helped extend the battery life so that he doesn’t have to have it constantly plugged in and take it on the go. It’s a good value for the money.

Pretty nice quality wasnt expecting to be as nice for the price but it works and the charging speed is as advertised with the power of the brick. The battery holds what it claims. I just wish it came with a sticky back you could use universally instead of be proprietary to the one bank but i cant complain about that.

I bought this for when I travel long distances and so far it hasn't burned my house down. It comes with a clip that snaps onto the Steam Deck that has holes cut out so the ventilation holes aren't covered. The included right-angle USB-C cable allows you to connect the battery to the Steam Deck while clipped on, but isn't that long and wouldn't allow it to be an effective power bank for other devices without a longer one. The battery slides onto the clip on the back of the Steam Deck, and the clip itself is thin enough so that it doesn't have to be removed to fit with the device inside the official case. A slight buyer beware as the Steam Deck won't fit into the official dock as long as the clip is on, so you'll have to remove it before docking the device.

The steam deck power bank clips to the back of your steam deck and is surprisingly not as heavy once it’s attached!Power bank was able to give me about 2.5 extra hours of game time (charging while playing a very hefty game) so you’re probably able to get even more out of it by letting it charge! The power bank fully charged my steam deck by the time it ran out of juice, leaving me with a whole couple hours left to game afterwards.I wouldn’t recommend this power bank if you actively use a case or vinyl skin for your steam deck though. The clamp is not adjustable, so it can damage your skin or just not work with a case on. However the power bank can be used as a regular bank as well without being attached, and if that works for you, then go for it!I WOULD recommend this if you don’t have a case or skin on your steam deck and wanted a more “portable” but functional power bank!The power bank can be used on its own as a regular portable charger. It only has one usb-c port so keep that in mind!Overall, this is a lovely item despite a minor design flaw. It’s a very powerful power bank, and that’s what matters in the end! I highly recommend.

Honestly this power bank has no flaws, It works great with my steam deck. But it works just the same with my switch and my galaxy zflip 4 so I keep it in my purse for whenever I need a charge!! Charging is fast and it's not too big to just pop it in a purse or a backpack. It comes with two chargers, one for when you're using it with your steam deck and the other is just a regular charger, it also come with a clip to easily clip on your steam deck so you can use the charger while you're on the go with your steam deck! If you're scared that clip will overheat your steam deck, it most definitely will not, it has a cut out where the vent is specifically made to make sure your steam deck doesn't overheat.I will definitely be using it everyday! It's definitely worth the buy even if you don't have a steam deck.

I bought it for my Steamdeck, but I don't get it, it works well on 100%, but when the LED shows 75% of charge it goes to 0% in less than 3 minutes, Is it broken? or is this the way it works?

Fits the steamdeck without a protective cover so I bought a cover I liked and cut the top off the bracket, I left the bottom as a guide to make sure it lined up with original mounting, I then super glued the battery mount to the case. It allows me to take the battery off and still provide protection for my steamdeck. Only downside is I can't remove the bracket or if I need to replace the case I'll have to try and strip the glue to move it or buy a new battery. I've used it for almost a year now.

Casing cracked on the back. Don't know why or if it's still safe to use. Only had it for a few weeks
