NEWQ 2-in-1 Steam Deck Battery Bank & Stand for Steam Deck/Steam Deck OLED, 20000mAh 65W PD3.0 Fast Charging Power Bank, Steam Deck Accessories, with Dual USB C Cables（Not Suitable for Case） NQ-SD-02

Exactly what I needed for my Steam Deck. I am now able to play Skyrim for days without needing to worry about charging my device every 2 hours!

Fits perfectly with my steam deck and functions as expected. Cradles the device perfectly. The battery life lasts a long while. The lighting of the bars is bright enough. The quality is most certainly better than expected for what I paid.

I really can't give the device a bad review, unfortunately, two things stopped my want for this accessory. (1) It is really heavy, it's almost like holding two steam desks at once. (2) I could have handled the extra weight, but I could not get the pack to mount to my steam deck due to the protective case I have on it.Apart from that, it came well packaged, has all the mounts and cables you need to attach to your already heavy steam deck.

This connects to the back of the deck. We enjoy the longer battery life for extended play.

Works as design but the company’s customer service is above excellent. I had a great interaction with them and they fixed the issue immediately.

was a life saver on plane trips and long train rides. best for steam deck and also use for my other devices.

Great backup battery for my Steam deck. Used it on our last flight and lasted long enough to charge my deck a second time around.

After a couple months the usb-c port stopped charging my devices. The USB works fine but the USBc no longer has bidirectional charging. Still useful and holds a charge well for a long time at a high wattage but it would be nice to charge more than one device at a time since this function broke. Probably not the smartest thing to be using a defective battery but that’s what renters insurance is for.
