Panasonic K-KJ55KHC4BA Advanced 4 Hour Quick Battery Charger with 4AA eneloop pro High Capacity Rechargeable Batteries

I purchased these rechargeable batteries and battery charger for my XBOX Series X Controllers. Eneloop has been my go-to rechargeable battery brand for years. They tend to last longer than any other brands in my experience. I went with the AA rechargeables instead of a dedicated XBOX Controller rechargeable battery because I can use them for my intended purpose, or anything that requires AA batteries like remotes etc... The best part is that this charger also works with their AAA batteries (which are sold separately).I can't speak on whether other rechargeable battery brands work well with this charger, but these batteries last a surprisingly long time and have not only met but surpassed my expectations. I bought them a few weeks ago and after an initial full charge, (which I'm unsure was even necessary,) I just now needed to swap them tonight, (and that's with multiple hours of gaming almost every night ).My top likes about this charger and the batteries are the battery life, ease of use, and how fast it charges batteries. The two batteries I swapped out tonight were fully charged within about 3 hours. The charger is user-friendly, with individual LEDs indicating charged/charging status of each battery. Overcharge protection gives me peace of mind that my batteries will charge fully without potential safety hazards. And it feels great not having to run down to the store to grab batteries every few days (or realizing I'm out during a heated gaming session.)This charger/battery combo is perfect for anything you have around the house that needs AA or AAA batteries and I would recommend this product to anyone in the market.

Really good price on these and these batteries last a long time in my game cameras

Product: Panasonic K-KJ55KHC4BA Advanced 4 Hour Quick Battery Charger with 4AA Eneloop Pro Batteries. (I state here as I have seen on Amazon where reviews don't always match the product or are generalized to all products from a manufacturer)Review Date: 05/07/2003Summary: I am very happy with this purchase.Pros: Top notch charger design, well designed batteries, fit all products, good power .Cons: NiCad (which has disadvantages due to technology), higher priced than cheaper NiCads, higher mAh means you sacrifice number of charges compared to cheaper NiCads (~500 versus ~2,200).Fit: I saw a couple reviewers who state the 'pro' batteries are bigger than standard AA batteries and don't fit in many devices. This is very inaccurate in my experience. I compared them close up to Energizer Lithium and they are identical in size. I can assure you that the Panasonic Eneloop 'Pro' AA batteries fit easily in my Roku remotes, Delta no-touch kitchen faucet power box, cheap milk frothier, Norelco trimmer, Microsoft mouse, August deadbolt lock and Serta adjustable bedframe emergency power box.Power: This is very subjective, but I would say these have about 2x the power of standard alkaline batteries but only about 2/3 the power of Energizer Lithium disposable batteries.Value: If power/longevity is your only concern, pay the steep price for Energizer Lithium. I noticed the cost of Energizer Lithium have skyrocketed, which is why I decided to switch to NiCad rechargeable. But if you want the best power to price, NiCads are far superior and I don't think you can go wrong with Panasonic Eneloop Pro.Alternates: If you don't care about power and only want high quality NiCad batteries, opt for the standard Panasonic Eneloop battery line. If low cost is your only concern, opt for Amazon branded. When it comes to NiCad, unlike many other products now days, you do get what you pay for.

These are great i use them for electric toothbrush, flashlights, xbox and meta quest 3 controllers. I've recharged them many times and they last as well as alkaline.

So good, I have two of these for my kids’ toys and all my gadgets that are heavy on AA or AAA battery drainage. I hate buying disposables because it’s such a waste to throw them out responsibly and it would still end up in a landfill somewhere. With Eneloop brand, I have owned dozens of AA and AAA batteries with only a couple of batteries going bad even after 5 years. The charger plays a part of this because even if you have a good battery, a bad charger can overheat and charge the batery too quickly it would degrade it much quicker. Using this charger and the original non fast charging chargers, it help properly charge the battery minimizing natural damage to cell.I haven’t timed the charge but conparing it to the original and a powerowl charger, this thing has the battery fully charged a quarter to half the time the other chargers can.

Nowhere in the packaging or instructions does it say to remove an invisible black paper strip on the + side of the Quick charger. I plugged it in and spent 15 min researching why my charger was not going through it's flashing routine and was about to return the kit as defective, when I finally found a reference online to the strip and removed it. Extremely irritating! Poor instruction writing, and the paper strip should be a contrasting color, like red and not black-on-black. Note that the normal pro charger does not hav this paper strip.My last sets of normal white Eneloop batteries lasted 9 years, so I'm hoping these will too. One star off for the issue.

Got two pairs of these for me and my GF to power two xbox controllers and two Quest 3 controller sets and they do the job amazingly. I have to recharge one pair maybe once a month with heavy use, and the charge levels have not degraded yet that I can tell. For the price, these can't be beat. The charger is great too, as it's compact and the lights are easy to read to know when it's charged, which compared to other brands does not take long. It's a 10/10 for me.

I bought this charger and batteries along with an order for 8 more Eneloop AA batteries to use in my photography speedlite flash units. I will likely be buying more as my budget allows, since I've been going through a lot of Duracells and Energizers lately. The speedlites won't work when the charge level of the batteries drops to about 1/2 charge. In use, these new Eneloop batteries are lasting way longer in my speedlites, so I will be changing out the batteries in all 9 of my speedlites (4 cells each) as soon as I can.just as soon as I can.

Excelente produto!

Ya llevo casi 1 año con ellas y son increibles. Realmente no se por donde empezar, asi que empecemos por el cargador. Compre el modelo "mas caro" y "reciente de la marca" por que es importante para mi tener baterias disponibles en cualquier momento y en una emergencia. Por eso me decidi por un modelo de carga rapida como este, que en 4 horas es suficiente para tenerlo al 100%. Ademas el indicador de leds es bastante util. Me hubiera encantado que tuviera la funcion de carga inversa para el telefono con su salida USB como el otro modelo, pero bueno. El material es bastante robusto y de buena calidad y no se calienta en absoluto. En cuanto al rendimiento de las baterias. este modelo ofrecia 4 pilas de 2550 mAh, lo cual me sorprendio, puesto que otras marcas ofrecen baterias con mayor capacidad, sin embargo y como lei en varias reseñas, la capacidad de reciclaje es la diferencia entre una buena bateria y una mala, y no se equivocan, puedes realizar unos 500 disparos sin miedo a que con el tiempo y el consumo empiecen a tardar a disparar el flash entre disparo y disparo. En absoluto se nota esa diferencia. Y eso era un problema con las baterias Sony que tenia, que con el uso empezaban a tardar en disparar el flash entre foto y foto, especialmente de noche. Asi que estoy muy contento con los resultados. Como punto extra, ests baterias retienen muy bien su carga, puedes tenerlas almacenadas un tiempo y cuando las uses ahi estaran para ti. Me encanta. Definitivamente comprare esta marca para siempre.

As pilhas chegaram bem rápido para uma compra internacional!Mas vieram com avaria. Na hora que foram colocar no carregador fizeram muita força eu acredito.O desempenho é muito bom dessas pilhas, comprei para usar em uma câmera Nikon, o falsh ficou top, e as fotos ficaram muito boas, a camera fica com desempenho profissional. E ela não descarrega rápido, ainda dá pra usar um bom tempo até acabar a carga.Em fim, é uma baixa pilha, se não a melhor do mercado! Recomendo demais!O poto ruim, é que não tiveram muito esmero na hora de colocar no carregador.

Son pilas caras sí, pero desde mi punto de vista son las mejores. Panasonic siempre ha sido de las mejores marcas en cuanto a baterías, y esta vez tampoco fueron la excepción.Yo las uso para un mando de XBOX y me han dado hasta 52 horas de uso con audífonos por par. Antes tenía unas Duracell recargables de 1300 mAh cada una, y la duración era de 12 horas con audífonos y micrófono y 18 sin ellos. Al ser dobles estas, se espera que duren el doble porque pues el par de Duracell eran de 2600 mAh mientras que el de estas es de 5000 mAh.Pero la verdad es que duran 3 veces más y lo mejor; tardan en cargarse por completo 4 horas nada más. Poco tiempo considerando todo lo que duranEl único pero que le pongo, y es algo estético, es que las luces del cargador no iluminan parejo a falta de más reflectores en las luces o láminas reflectores. Sólo es un gusto estético que tengo en lo personal pero fuera de eso todo está excelente con estas pilas.

Llevo ya varios años utilizando baterías recargables Eneloop, ya sea para trenes eléctricos navideños, para los controles remotos de las TVs, para el teclado de mi PC o el Mouse. Con el cargador Panasonic de modelo anterior ( BQ-CC17 ) las baterías se cargaban muy bien pero le tomaba varias horas y nunca sabías cuanta carga les quedada a las mismas pilas ni cuanto tiempo tomaría la recarga. Por ello compré este nuevo modelo de cargador el cual desde el principio con una guía de colores led te dice cuanta carga hay en la batería y te das idea de cuanto tiempo le falta para una carga completa. Además en una batería completamente descargada este cargador termina la tarea en la mitad de tiempo que el modelo anterior. De verdad lo recomiendo. Espero te sea útil mi reseña.
