Rechargeable Controller Battery Pack for Xbox One/Xbox Series X|S, 2x6660mWh Battery Pack with Type-C Charging Cable for Xbox One/S/X/Elite Controller

They're a little snug going in, but they work great. The battery life is pretty good. I'm not a hardcore gamer, but I've only had to charge the battery once since I got them about a month ago. The seller doesn't show it in the product pics, but you can put the battery cover back on you controller just fine with the battery pack installed. Even if you've lost the battery cover, the little bigger is in there so securely that I don't think there's any danger of it falling out during a game. I almost forgot to mention, it's a two pack! I was fine with the price when I thought it was just for one, but for two? That's one heck of a bargain! I would highly recommend that anyone with an Xbox One controller buy them. They'll pay for themselves in savings the first time you recharge them instead of paying $6-$8 bucks for a pair or two of AA alkaline batteries.

Great product, especially for the price. The battery’s are well designed so they fit well. Perfectly compatible with my Xbox controller. Long battery life even with headphone use. Charging is easy and can use any USBC charger. With there being two, you can charge one while u use the other. Highly recommend this product.

Best batteries that I have used for Xbox. Surprisingly durable. The batteries are highly simple to install and the design is amazing. They work so well!

They are working great so far! I game on Xbox about 3-4 hours a day, at that rate a fully charged battery lasts about 5-6 days. They charge quickly and can simply be plugged into the front or back USB port on the Xbox. Only downside is there is no low battery warning, they just die so that can be pretty inconvenient while gaming. Luckily it hasn't been an issue yet but definitely can be especially when playing multiplayer.

Perfect packs for an amazing price. You get 2 packs for only like $8, which is basically what you would pay for a decent set of AA batteries. However, these recharge and last a long time. I played COD all night long and never had to swap packs one time. So, for the price, keep a spare for your controllers. You can recharge these via the controller or the USB C that plugs directly into the battery pack.

It works pretty good was on a budget and was tired of having to buy batteries. Comes with 2 and has definitely saved me some money over the past few weeks.

works great it designed to compatible with xbox and last a long time. easy to install. fits in the xbox controller. one time charge last over a week. nice solid design woth green light

I ordered these batteries because I didn't want to keep buying disposable ones anymore, and I was pleasantly surprised. I've been playing at night for over a week and a half, and the battery still hasn't run out. It's incredible! The price, the quality, the battery life—everything is perfect. The only minor issue is that the controller's battery cover doesn't fit properly when the battery is in, but if you don't mind that kind of detail, it's perfect. They're super affordable, and the package even comes with two... I highly recommend them!
