GKHERD 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

Charging speed is great. Lasts a long time between chargers. Easy to replace and plug and play. Fits great with original Xbox controller!

I waited a few months to write a review to see how much I like the product and I can say that this is a good product for your buck. It comes with two of the packs so you can have one charging while the other is playing which means for me I never have to use batteries for my controllers which works great for me. It fits pretty well as long as you look at the instructions. I will say they typically last few hours of consistent play but I never measured how long. Overall I think they are pretty good and worth it!

Great product, If you leave inside of the xbox controller it will discharge as any battery. About 2-3% a month. I love the capability of charge using my xbox controller charging port and having a port on the battery you can charge the second one as well. If the cable provided is short, just get another cable or use a battery pack! Amazing Deal and I hope I can buy more products from you again!

Update: if you take vibration off, they last for a very long time. Though sometimes the controller will disconnect and then charging it for ten minutes will get the green light on but its not fully charged. All in all its great. 1 star less due to vibration limitation.Initial reaction: They work for maybe 45 minutes and then when they die you cant even charge and play, they need to have a charge first and then you have to let them charge a bit before you can play while charging. For the price, its not the worst but anyone saying they get 15-30 hours is absolutely lying through their teeth. So two battery packs that get you maybe an hour and a half - 2 hours is not the worst ever though still not good.

Those rechargeable batteries for xbox are the best. I have tried many batteries and they don't last long .but those batteries stay longer than I thought. With one charge they run 3-4 days .my kids play all day now the school is over.they are easy to install like normal batteries. They are fast charger and they connect very well.they have very good performance

Item looks and is described correctly in the listing. The battery packs arrived in a simple box with a usb-c cable for charging. Charging was as simple as plugging in the included usb-c charging cable into the battery and the other end into an adapter that outputs 5vdc @ 1 or 2 amps. Being Lithium Polymer cells means longer output power before it drops and needs to be charged. Other cell types, such as NiMh drop voltage as the battery drains. The box has a UL, CE, and FCC symbol on it; which the description says it has passed all three certification entities. The battery dropped right into my Xbox One controller and fit perfectly. I've been using these batteries for about a month now and have not had any issues whatsoever. Longevity does vary depending on how you take care of your LiPo batteries. Do not store them fully charged or fully depleted; 3.8v is the sweet spot and keep them between 68 to 77 degrees Farenheit and they will last long.

I didn't read the description. I didn't know 2 came with it lol. I am VERY pleased with that. It also tells me my battery life while I'm playing my Xbox. I can check in the top right hand corner. I've seen some reviews that said you couldn't but it let's me.

Battery life is greatA bit snug in the controller so just be gentle.I absolutely hate how it doesn’t tell you when it’s about to die. Super annoying when the controller disconnects.Other than that they are great.
