Nyko Xbox Power Kit Plus for Xbox Series X|S/One – Rechargeable Battery Kit with 2 Batteries, Black Covers, 10-Foot USB-C Charge Cable – Ultimate Xbox Accessories – Power, Charger, & Battery Pack

Works great
Wish the battery life was better but they do the job.

lives up to nyko standards
day 3 of use: It came well packaged and damage free. Product is sturdy and of high quality. The instruction are less than expected, but the only thing missing is a description of what the LED colors mean. I just assumed red is charging and green is charged. I use them in xbox one controllers so, it’s good that the product comes with two of each type of covers. The c-type input is much more convenient than I thought. I chose these to replace a dead battery with old style charging cradle (apparently they don’t make them any more, I wasn’t sure if the new batteries would be friendly with it) Good pricing, very long cord included (using already owned cord on mine). Not sure how long the charge will last yet. I played for 4-5 hrs over the last two days and will do so tonight. I haven’t need to charge again yet. Old batteries would last between 20-25 hrs between charges (same brand). If these last half as long as the first ones (lasted 10 years give or take), I’ll be satisfied.

Not compatible with Nyko charge block
I own a nyko charge block which I use to charge my original Xbox one controllers. Before purchasing this charge kit I asked if it is compatible with the Nyko charge bock, as did at least one other person (See Q&A section). The manufacturer responded with a definitive yes. On receiving the charge kit the first thing I did was test to see if it worked with my charge block. Neither the LED on the charge block or the battery itself lit up indicating that the battery pack was not charging. No matter how I situated the controller the LEDs would not light up. I even tried putting the battery alone (not inside the controller) on the charge block but no difference. Despite all this I left the controller on the charge block to see if it would charge even though the LEDs were not on – no charge. I specifically purchased this charge kit over the first party Microsoft charge kit because I was told by the manufacturer that it is compatible with the charge block. Either the manufacturer is being deceptive or they have a limited understanding of their own products. The only bright side is that the battery does charge when connected using the included cable. This, however, is not the solution I was hoping for. I cannot recommend this product to anyone who is hoping to use it with a Nyko charging station.

Why did I not buy this earlier???
Have been using duracell rechargeable AA batteries that get maybe 75 to 100 cycles. These are rated at 1000, comes with a set of 2. Fits xbox and xbox series s/x. So 4 covers. Super long USB c type cable. I may never have to pause a game again. Only thing to remark. They are 1100 mAh (faster discharge rate) and 2.4volt (weaker wireless signal.) VS regular AA is 2500 mAh 1.5v. Though I’ve read the controller has a voltage regulator to produce same signal power regardless… we’ll see.

I was reluctant to pick up the power pak considering previous reviews voicing compatibility issues with Nyko’s older XBO Charge Block. My experience so far has been great and I’ve been able to charge a Series X controller with the battery cover installed on a XBO Charge Block (see pictures). If you’re like me and want to continue using your existing charging hardware with the newer Series-controllers, this battery kit will fit the bill!

Good product

una maravilla por fin olvidarte de las baterias , duran un buen tiempo , tardan algo en cargar pero no mas complicaciones , hay que ponerlas con cuidado por que las tapas traceras se batallan un poco en insertarlapero en resumen buen producto , buen precio.
