SiWiQU 20000mAh Magnetic Power Bank for ROG Ally, 65W Fast Charging Portable Battery Bank, External Battery Pack with Detechable Magnetic Back & Dual USB Cable, Support 30W Turbo Operating Mode.

I've read all the reviews and I disagree with most complaints.... you can reach the macro buttons (rear buttons) with no problem. It is heavy, it's a giant battery, it's gonna have some weight, not too heavy tho. As seen in the picture I used electrical tape to hold the small right angle cable on it (I was afraid I'd loose it) as it needs taken off to charge, if I had to suggest a change is a second usb-c to charge while using, but that's the biggest problem I can find but fixed with a little tape, excellent product I recommended it to my son for his, and to you! Oh, and if you play at full 30w power and lay it on a pillow the battery will get hot, but other than that there are no heat issues. I've used for about 6 months, seems durable and adds a tom of high watt play time, I'd also recommend a second 65 watt charger to charge your rog ally, and your battery at the same time, also charges pretty fast with a 65w+ charger. Magnet holds great, obviously a strong neodimium magnet, it can wiggle a bit if you twist the battery separately but there is room to hold it without holding or touching the battery. I do recommend!

Being able to play your games for more time while on the airplane makes it worthy. It works fine, it let's you play your games at 30W while charging it. The magnet is strong enough to keep the battery holding but sometimes when you move it it can fall, so be careful.It charges really fast and it is easy to use. It is a little bulky but still easy to store in your backpack.

So good and charged my ROG when needed, only issue that I came across is my wife steals it. Such a good charge and it a fast charger so it charges our dead phone super fast.

I do enjoy this product very much. It definitely makes the gaming on the go experience a lot more fun. It does make your ROG Ally a little bit heavier, but I don't mind that much. It keeps my handheld charged on the go. Theonly downside is that you can't use the battery with the clip with a case on your Ally, but I guess that's alright. Still does a good job.

Great charger i use it alot and it lasts forever i recommend this if you game on asus rog ally

i love my battery, it extends the charge of my rog ally by around 3-4 hours it seems, depending on the game. attaches easily with a very strong magnetic hold. works great and charges quickly too! plus it doesn't have to be used for only the rog ally, and can charge my phone, ipad, and other devices easily. highly recommend it!

Been using this gadget on my Steam Deck! I don’t use the actual holder but I do use the long cord they provide. It’s much more comfortable that way as it won’t add any extra weight. The battery gives me an additional 2-3 hours on gaming sessions! Very functional, and the size really shows how powerful the battery is. It’s a must-have if you’re a true gamer :)

This thing is just too big. It takes up the entire bottom portion of the rog Ally when docked, and it doubles or triples the weight of the device. It comes with a tiny little USBC right angled cable. Actually it comes with three cables but only one is capable of pushing enough charge for the rog Ally. Why the other two are even included is beyond me. But anyway, the output Port on the battery is right where the back paddle button would be. So if you use this device with the battery you literally cannot use one of the two back paddle buttons, I hope you don't rely on them!It's heavier than ****. It completely throws off the weight of the device - it always wants to tilt in a way that makes it hard to see the screen. It's uncomfortable to hold. And it's by a brand that has literally no history of safety or anything. In fact it has no history at all, the company was made up solely to sell cheap merchandise on Amazon.Oh, and when plugged into the Ally using the provided "100w" cable, The Ally complained about The input power not being high enough, and the battery slowly discharged as I played games. So it doesn't even provide enough power to actually run the damn thing. All in all, it has zero benefits.Buy and Anker Prime battery pack. It is truly capable of 100 w charging, in fact the newest version is capable of up to 200 w on two USBC ports, or 140 w on one port. Also it has a lalrger 24000 mAh battery and it's produced by a company who has years if not decades of history of successful power and battery device making.Stay away from this dangerous, useless, off-brand piece of crap.
