CEF27 ION speed 4000 Hi-Performance Charger, Includes 2 AA and 2 AAA NiMH Batteries

Takes a bit of time to charge batteries, but is reliable and the batteries seem to last long. Price is not bad. It's small enough to pack anywhere if needed. The included batteries definitely made the purchase worth it.

The Duracell Ion Speed 1000 Battery Charger is a well-designed, highly reliable charging solution that brings the brand’s reputation for durability and consistency into the rechargeable world. From the moment you open the packaging, it’s clear that this isn’t a cheaply made charger. The build quality feels solid, the materials are smooth and sturdy, and the layout is clean and intuitive. One of the biggest strengths of this charger is engineering. The Ion Speed 1000 charges quickly—noticeably faster than many budget chargers—while still maintaining safe, even charging across all bays. The independent charging channels are a major plus, allowing you to charge one battery or several without affecting performance. Overcharge protection, smart detection, and auto shutoff all work exactly as expected, extending the lifespan of your batteries and adding peace of mind. The included four pre-charged AA batteries are a great bonus. They arrive ready for use, hold their charge well, and deliver strong performance in high-drain devices. The only small drawback is that it’s sometimes hard to differentiate these rechargeable Duracells from the brand’s disposable AA batteries at a glance. A more distinct visual cue would make quick sorting easier. Charging performance is excellent. Batteries consistently charge to full capacity and retain power over long periods between uses. For everything from flashlights and remotes to game controllers, kids’ toys, cameras, and cycling accessories, this charger keeps devices running smoothly with predictable reliability. Compared to higher-priced chargers from specialty brands, the Ion Speed 1000 holds its own. It offers comparable charging speed, better long-term reliability, and well-designed safety features—all at a more accessible price point. The compact size also makes it great for travel or keeping in a drawer without taking up valuable space. Pros • Solid engineering with fast, safe, efficient charging • Independent charging channels for flexibility • Durable build and clean, compact design • Included pre-charged AA batteries perform exceptionally well • Excellent value compared to premium chargers Cons • Rechargeable Duracell's could use a more distinct visual indicator to differentiate from disposables If you’re looking for a dependable, well-built battery charger backed by a trusted brand, the Duracell Ion Speed 1000 is an outstanding choice that delivers speed, safety, and long-term value in a compact package.

Reliable and long-lasting — these Duracell Coppertop AA batteries have become my go-to for all the small devices around the house. They hold up well in remotes, clocks, and flashlights, and I like that they’re backed by a brand that’s been trusted for years.

I bought the Duracell ION SPEED 4000 Hi-Performance Charger (CEF27) mostly for home use, and it’s quickly become my go-to solution for keeping both AA and AAA batteries ready to go. It comes with 2 AA and 2 AAA NiMH batteries pre-charged, so you can use it straight out of the box—which is a nice touch. The charging time is very fast—I usually get my AA batteries to around 90% in a little over an hour, depending on their capacity. The charger works with any NiMH batteries, not just Duracell-branded ones, which adds flexibility if you already have rechargeables from other brands. There’s also a simple LED indicator that shows charging status, and the charger turns off automatically when charging is complete. I appreciate this both for safety and for preserving battery lifespan. The included batteries have been great so far—they hold their charge well and haven’t shown signs of capacity loss after multiple uses. According to the specs, they can be recharged up to 400 times, and if that holds up, this kit will easily pay for itself. Final verdict: If you want a dependable, quick charger with quality batteries included, this is a great option. It’s compact, efficient, and easy to use—a smart upgrade from slower, older chargers.

Excellent quality, and you can recharge over and over again without buying packs of batteries, you can instead reused them and your not going to create more waste using the regulars 👌 I have been using them for a long time and I love them!

These are a wonderful choice to avoid the waste of conventional cells HOWEVER they only work reliably in limited applications: 3-4 cell flashlights=super!, TV remote control=useless! Haven't tried in wireless telephones because they use specialized batteries. Our big LED wall clocks advise not to use them, but they work fine anyway. These cells are well worth the investment for use in appliances that have compatible current demands. Test first and have a few conventional cells on hand in the event that rechargeables simply aren't up to the task.

Outstanding durability in my LED headlight. Long lasting charges and very bright beams, night after night, week after week.

Really good batteries and bathed maintain a charge for quit a long time. Impressed.

Excellent Product...very useful and value for money

Excelente producto muy durable y se carga con mucha facilidad

This purchase through Amazon was a fantastic price. You get 6 rechargeable batteries, when most packages come in 4’s. There are so many possibilities to use them in any device- for me it’s 3 portable telephones 👍

It’s a basic charger for AA and AAA rechargeable batteries. LED lights let you know the status of the charging batteries. It’s basic and it works perfectly fine with all of the rechargeable batteries that I have. This charger kit also comes with 4 rechargeable AA batteries which was nice.
