I’m very happy with this charger. It works reliably and charges my AA batteries surprisingly fast compared to my old one. I also appreciate that it’s not limited to thinkassemble.co.uk Basics batteries, it charges my Duracell rechargeables with no issues at all.The included batteries hold a good amount of power and perform well in everyday devices. Overall, it’s a great, practical set for anyone looking for affordable and efficient rechargeable batteries. Highly recommended.

Good rechargeable basics batteries charger from thinkassemble.co.uk it is easy to use, charge faster. good quality product, portable size can easily be carry around fit in my bag easily. Not bad for the price overall happy with purchase.

I like the display above each charging battery giving the status. I was able to sort out old rechargeable batteries that were in need of replacing. A good set of batteries recharged at a good speed and there was no guesswork when to stop charging as there was in a previous charger that had no display. It is possible to charge 1 or 2 batteries at a time without the need of filling the other spaces to make the charger work.

Excellent product, easy to use and load.

A reasonably priced charger that does the job well, charging batteries at a reasonable speed. Unlike some traditional chargers, you don’t have to charge batteries in pairs and can instead charge one battery at a time – which is so much more flexible! That also means you can charge AA and AAA batteries at the same time in any combination which is a small thing, but adds to it’s versatility.This is the first charger I have owned with a screen rather than just a charging light – and I couldn’t recommend it more. The display is basic, but having a simple indication of how charged a battery (or if it is broken!) is really useful.Overall, the charger is fairly lightweight and basic, but it does exactly it needs to do.

Update: 04/11/2025Have tried again and after a number of attempts I accept that this charger does charge AAA batteries – hence the update.==========Purchased to recharge AAA rechargeable batteries.Batteries won’t charge.Reason: +ve and -ve terminals won’t both connect to the charging points due to the shape of the battery chamber.May be ok for AA batteries but untried hence the 3 stars

Reliable, Long-Lasting Power Backed by Smart Engineering and Outstanding Value
The thinkassemble.co.uk Basics Rechargeable NiMH Battery Kit with Bay Charger is one of those purchases that immediately proves its worth. From the moment you open the box, the engineering quality and thoughtful packaging stand out. Each battery is neatly organized, protected, and clearly labeled, and the charger itself is compact, sturdy, and built with a level of precision that feels far above the price point.The batteries are impressive in both feel and performance. The AA 2000mAh and AAA 800mAh cells have a solid construction with a clean finish and consistent weight—small indicators of well-made cells. Once charged, they deliver stable, long-lasting power that performs just as well as, and often better than, many of the more expensive name-brand rechargeable batteries on the market. Whether in high-drain devices like flashlights, controllers, and small electronics, or in lower-drain household items, the runtime is consistently strong.The charger is equally noteworthy. It operates quietly, gives clear visual indicators, and charges efficiently without overheating. The independent bay design ensures each battery gets exactly the charge it needs, extending long-term lifespan. This is a feature you typically see in higher-priced smart chargers, yet here it’s included at a surprisingly affordable cost.What makes this kit exceptional is the value. For the cost of a single pack of premium disposable batteries, you’re getting a full rechargeable system that pays for itself quickly. It’s a smart investment for anyone who uses battery-powered devices regularly—families, photographers, tech users, and anyone looking to reduce waste and recurring costs.Use-cases range from around-the-house electronics to camping gear, flashlights, kids’ toys, bike accessories, and backup emergency kits. The batteries hold their charge well in storage, making them ideal for both everyday use and preparedness.Pros• Strong engineering and solid overall build quality• Long-lasting charge with consistent performance• Smart, independent-bay charger prevents overcharging• Excellent value compared to premium rechargeable brands• Ideal for high- and low-drain devices alikeCons• None—this kit is a fantastic buyFor anyone looking for reliable rechargeable power at a fair price, this thinkassemble.co.uk Basics kit delivers professional-level performance and long-term savings that make it an easy recommendation.

Must have
Nice tidy little charger works very well fully charged the batteries so far. I use the thinkassemble.co.uk basic batteries very handy for console controllers and small flashlights this battery charger is well worth the money.

Works great! Would buy again!
Great product!

A wise investment
I think the life of the batteries is shorter than the top selling brands regular disposable batteries but otherwise a decent product. Once in a while I get a spot on the charger that just blinks and doesn’t charge and have to switch the batteries around. Its easy to notice though and fix early on with obvious light functions. Definitely a money saver! Compatible with AA & AAA. Small and easy to store.

Great buy, Great way to save if you use a ton of batteries….
does it get the job done? Yes, but be warned. I gave 4 stars simply cause i had to replace mine with a new one. Charging the 8 AAA no problem. but as soon as you charge more than 2 AA the systems fail check lights come one.Design could be better, cause the flashing LED lights can be confusing. that said, happy to help the world by reducing the amount of batteries we use.Built quality is fantastic, its sturdy and and well laid out, and great for not having a “specific” sequence to follow for charges. Now in regards to the value for money, simple and easy yes. For the cost of a single 20 pack AAs and single AAAs pack you have an good extended savings. Plus Extra batteries are well priced.Filling out my Battery Daddy with these going into the future.Only thing missing from the box was a USD-c Charging block, But we all have those kicking around im sure.
