Panasonic BQ-CC87ABBA eneloop Advanced Individual Battery Charger & Panasonic BK-4MCCA12FA AAA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 12-Battery Pack

Handy to have as it charges on any source

So far it's the best charger for batteries I have ever had, I like that you can not only charge your batteries but you can also use it to charge your phone if you needed to.

Excellent compact plug-and-play charger. No need to worry about balance charging, overcharging, or other factors to prevent your batteries from burning your house down. You can charge any number of batteries (up to 4) in any order/configuration with no worries, and also auto-shutdowns when batteries are at optimal charge. I tested this charger with the Ikea Ladda AA and AAA NiMH batteries and they charge them perfectly. It's also extremely convenient to charge via micro-USB at my desk.The reverse battery-pack function is also pretty neat but not something that I utilize that much. The only downside would be being limited to charging 4 batteries at a time, but that was not an issue for me. All in all it's a great charger from a reputable company in the rechargeable battery space and I would implore others to not hesitate spending the extra money for this charger over others on the market.

I use a crazy amount of rechargeable batteries, and have 3 chargers: one that came with an Eneloop kit, a LaCross BC-700 (my fav), and this. I really wanted this to be my favorite, since I always has USB ports available to power it (and strongly dislike wall-warts).The problem is that it decides (via blinking red led) that the battery is dead. This includes *brand new* Eneloops, right out of the package, that I want to top-off before first use. The other chargers are just fine with them.At best, I should "reinterpret" blinking-red LED to mean "try one of the other chargers, I'm not interested".

Purchased this primarily for use in an RV where storage space is limited. Replaced another charger that was bulkier and had a wall wart transformer. A pair of these Panasonic chargers take up about as much space as one of the other chargers plus transformer.Charges relatively quickly when connected to a 2A or greater USB charger. Charging on an older 0.5A USB charger would likely take a lot longer.Individual charge channels are a plus. The charge status lights are adequate for conveying the charge state of the batteries.The power bank feature does work but I need to do additional testing. With 4 fully-charged Eneloop AA batteries (theoretically around 8,000 mah) I was only able to partially charge a cell phone with a 4,000 mah battery. Need to try this again when I can pay more attention to what's going on. Nice feature to have for emergency use.Like an AC-powered Panasonic AA/AAA charger I have, not wild about the way AAA batteries fit at an angle. Seems like they would be prone to falling out if the charger is vertical, but so far they seem to stay in place OK.When we aren't traveling I use it indoors for charging batteries from various devices.All in all, it performs very well . I am very pleased with this charger and purchased an additional one for the RV.

- It's a smart fast charger, means it actually detects how much charge is in each battery. A lot of chargers that claim "auto stop", but it could just in fact rely on a timer. Would take the same time to charge a flat one and a full one, which overcharging is not good.- Just dead easy to use, with coloured light show you how much charge is in each battery.- Detects dying batteries- I've never tried this but it should works like a power bank, USB power output with AA batteriesI had been using it for almost two years, never failed me once. Charge fast, reasonably small, shows you charging progress with LED lights without overly complicated informations.Just beware that if there's less than 1A of USB power (too old cable, too old USB adapter, some USB on computers) it would resort to slow, fixed 13 hours of charging. It shows with flashing green LED lights when it is in this mode.

The charger is great, but it is too sensitive to the state or condition of the batteries. I have several old batteries that don't perform like new, but they are clean and fully functional. I had problems with all those batteriesI'm not sure why this happens, but old batteries still charge without problems in "less smart" chargers. I would have liked to know this before buying the productIf you have new high quality batteries it is an ideal charger, but if you have old batteries I would not recommend it at allEdit: I had not noticed that my devices were malfunctioning due to too old batteries (for example, in an xbox one controller I was losing signal, I thought it was the bluetooth receiver but in reality it was the batteries)Now makes sense to me that the battery chargers to give those warnings

I can charge 12 - 2000mah NIMH batteries with this in the time it takes my older Nitecore I4 Intellicharger to charge 4. This one is not built as heavy duty but I suppose if I find a suitable protective case/pouch, it's light weight would come in handy when transporting it. All in all I'm satisfied with this purchase.

Carga de manera muy rápidas las pilas, en menos de 4 horas ya están cargadas, lo que no me gusta es que sea tan "inteligente", no me deja cargar algunas pilas por que me indica que están fallando, pero otro cargador las carga sin problemas.
