I love this charger so much it hold so much juice/charge and it'll keep my devices charged all day long.
Pros: long battery life, sturdy, fast charging cable, c-type cable to fit a wide range of devices
Cons: heavy, bulky, the clip to hold it on to the device only works for steam deck
All and all its a great charger

This will increase your gaming time x2 on the Steam Deck Undocked and it fits rather easily on the back and comes on and off really easy. You don’t need to let it live on the Steam Deck which is another bonus!

I always have issues with battery life on my steam deck. This power bank is spectacular! Easy to use, not too heavy and adds a ton of charging power on the go. Highly recommend to anyone who games regularly or travels! It charges so fast too!! Love love love this power bank! It can also charge your phone!!

First I want to say that the packaging was superb. The power bank was wrapped up really nicely and the box it came in was sturdy, so guaranteed it won’t be scratched once it arrives.

The power bank itself is so wonderful! There’s dot indicators for how much it’s charged, and it comes with 2x chargers!

Of course, this is a must have if you do have Steamdeck. It comes with a snap back so you don’t even have to worry about holding it!

Overall an amazing product.

I don't have a steam deck, but I use this on my nintendo switch and phone. It charges SUPER fast and is very effective. It's a high quality product and made very well. I highly recommend especially if you're someone who travels a lot. It is a bit heavy, but doesn't get too hot and honestly it's really nice. I also like that it's compact so you can take it with you anywhere. I highly recommend.

This has been a life saver for my traveling needs. I have an iPad and a Nintendo Switch that I use constantly and this has been perfect for me to not worry about having my charger or somewhere to charge my electronics. :)

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 have no complaints, this portable battery is very reliable. I usually use it for my switch, phone and tablet and it charges very fast. The battery itself is in my opinion pretty light compared to other portable batteries I've used but it's still pretty solid in weight and doesnt feel cheaply made at all. I like that it came with extra usb type c wires and with the detachable mount even if i currently don't have a steam deck(planning to get one soon). Overall, this is such a reliable portable battery and lasts for a long time. The indicator lights are also very useful so that I know how much power the battery still has.

As soon as I picked it up I felt how heavy it was. It feels incredibly durable, sturdy, secure, and high quality. The battery life has lasted several days with constant plays on my switch, phone, table, and controllers. It's a decent size but still good enough for it to be portable, fitting into any bag, pocket, or purse 笙｡

Definitely worth the price.
Great quality, high speed charging for anything that takes USB-C. It's perfect for my Steam Deck ♡
I personally like using mine without the back mount only because of the case I have.
Other than that, this is amazing ✨️

This is a definite needed accessory for your handhelds! It is specifically designed for the SteamDeck but I also use it for my Nintendo Switch when I'm on the go. I've been using it for road trips but it was also important during Hurricane Idalia. This one power bank powered up my Nintendo Switch, SteamDeck, tablet and cell phone!
The minute you hold this in your hands you know it's a PREMIUM product! Extremely well built!
It charges quickly via USB-C. It includes a long USB-C cable for charging devices and a shorter one for the SteamDeck. It clamps on the back of the SteamDeck using a bracket so it stays in position.
I'm thinking about getting another one just because it's so necessary nowadays to keep your devices charged!

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.

This is a perfect device to have for when I'm headed to work and wanting some extra juice for my switch, also perfect for long car rides and camping trips 😁✌🏻

Pretty heavy but its a long lasting battery

Brilliant no problem what so ever

Definitely extends play time for the steam deck. Charges quickly and good for traveling. It does significantly add some weight to the deck and takes some getting used to. The most disappointing thing to the battery is you have to remove your protective case in order to use it.

Honestly, I didn't know what a Steam Deck was until I ordered this power bank. I wanted to have a large power bank in case of power outages so I wouldn't have to worry about recharging devices.
This power bank is 20,000mAh, which will charge my phone about three times. I use a USB 4.0, which charges my phone at super-fast speed. I can also use it to charge my Dell laptop.
It's a large power bank, just a bit smaller than my Galaxy S21 Plus, and it has some good weight to it. The LED lights indicate how much charge it has left. There is just one USB-C port for power in and power out, although you can connect a hub and charge more than one device at a time.
I really like that it's so portable and I can take it anywhere, especially when I sit outside on the porch. When it's not in use, I plug it back in so it stays full for an emergency. It has overcharge, over-discharge, short circuit, overcurrent, and a chip that identifies and adjusts to what you're charging so you don't have to worry about anything.

I like the look, the power and the overall *feel* of this product. It's compact to bring it with you to places but also to charge some power heavy devices (Switch... and I'm going to test it on my chrome book as well.)
So far it's worth every penny. It's really good.

My boyfriend got a Steam Deck last year and one of the main issues we've had is battery life. If it's not constantly plugged in it only seems to last an hour or so, which makes it hard to play on the go. This has helped quite immensely. It gives us a few more hours of play time while we're on the go and we can have it charging while we play. It comes with a clip to attach it to the back of the deck, but the main downside to that is that the battery is quite hefty and makes the deck heavier with it attached. Not as big of a deal though if you set it down and use a separate controller though. You can also get a much longer cord to attach it if you don't want it clipped on as the one provided is too short not to. But overall it's great to have a battery big enough to let us play the steam deck while we're traveling.

This power bank has been a godsend. I had to travel a good bit lately and when on flights this actually made it so I could go a whole flight and use my Deck like it was a proper portable system playing elden ring and monster hunter. it is weighty but not awful. the closest thing to a gripe I could have is it takes forever to charge with anything other than the deck charger. a must for Deck owners who travel.

Stupid, I know, but I don't own a steam deck and just use this as a power bank for my phone etc...
For my needs, it's just mediocre. Pretty bulky only a single USB C port. I expected it'd have two ports (the second being for charging the device). But that's my fault for overlooking that aspect.
It does what it's supposed to to though. Comes with an adapter for the steam deck attachment, has a display showing 25, 50, 75 and 100% power markers.
I've yet to run the power bank dry, so I can't say if the capacity stated is accurate, but so far it seems pretty close.
Should serve you well if you're looking for a steam deck battery. If you're just looking for a power bank, look elsewhere.

This thing is a beast! It's super-chunky, but if you're okay with that, it's the power unit for you. The mount doesn't really get in the way of anything and holds the battery well. Great addition to the Steam Deck for extra juice.

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.
