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. Read more

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. Read more

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: 05/07/2003 Summary: 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. Read more

Batteries lasted me through an entire wedding! Easy to use. The quality is great. I’ve had the less powerful version of these batteries, and I’ve been overall satisfied with how they are built. Great value for the price. They do charge significantly faster than the other ones. Read more

This is a decent set of batteries and a charger. Eneloop batteries are among the best, IMHO. One thing I noticed though is that the AC plug is offset to the end of the charger so that when plugged into a wall outlet the device is trying to rotate to the right. Eventually this could cause a failure in the charger. Read more

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. Read more

They last for a very long time before needing recharge. The last ones I bought 2 years ago are still working today but it was time for new ones. They are a great value for your money. At first they man be a little costly but they money you save from not buying regular batteries in a year make it well worth the extra dollars. Read more

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. Read more
