The XTAR L8 Box is a combined battery charging and storage case designed for AA and AAA rechargeable batteries. It supports charging and storing up to eight batteries at a time and retails for around US$30, positioning it as a more design-focused alternative to traditional battery chargers.
Build quality
The XTAR L8 is made primarily of plastic, but it feels solid and well assembled. The vertical charging design allows the batteries to be hidden beneath a magnetic lid, giving the charger a clean and minimal appearance that fits well on a desk or shelf.
The magnetic lid aligns easily and stays firmly in place, while still being easy to remove when accessing the batteries. Overall, the build quality is good, and the design clearly prioritises neatness and everyday usability over a purely utilitarian look.
Features & Usage
Most battery chargers place batteries horizontally and are often limited to four slots. The XTAR L8 takes a different approach by charging batteries in a vertical orientation and offering eight charging slots in a single case. By default, it supports AA rechargeable batteries, including both 1.5V lithium-ion and 1.2V Ni-MH types. AAA batteries are also supported using the four included adapters, allowing you to mix AA and AAA batteries during the same charging session.
Each of the eight slots has its own LED status indicators on the lid, showing the charging progress of individual batteries. This makes it easy to monitor charging at a glance without removing the lid. The XTAR L8 is powered via USB-C, which adds to its convenience, as it can be powered by a wall charger, computer, or power bank. This makes it suitable not only for desktop use but also for travel.
As with other XTAR chargers, the L8 includes intelligent charging features such as multi-stage charging and protection against overheating. There is no display or detailed charging data, but the charger is clearly designed to be simple and reliable rather than feature-heavy.
XTAR 1.5V AA 3960 Rechargeable Li-ion Battery
The XTAR L8 was tested with XTAR 1.5V AA 3960 rechargeable Li-ion battery. At first glance, the XTAR 1.5V AA 3960 looks like a normal AA battery, but the positive terminal has a small LED indicator that lights up when tapped. It’s a simple idea, but also one that immediately makes sense. Instead of guessing whether a battery is half-full or nearly dead, a quick tap gives a visual indication of the remaining charge. In practice, this feels far more useful than I initially expected.
With a rated capacity of 2500mAh, these batteries are clearly aimed at medium- to high-drain devices, and they have been in my Aqara smart door lock so far no issues. XTAR rates the 1.5V AA 3960 for over 1,500 charge cycles, which, if even close to accurate, makes these batteries a long-term investment.
Charging speed is another area where XTAR 1.5V AA 3960 stands out. A full recharge takes around 2.5 hours, which is noticeably quicker than many traditional rechargeables. While I did not need to charge it yet, this makes it easier to top up batteries between uses rather than planning charging cycles far in advance. Especially for my use case of smart door lock, the faster charging reduces friction and makes rechargeables more practical overall.
Conclusion
Overall, the XTAR L8 is a practical and thoughtfully designed charging solution. The combination of charging and storage works extremely well, and its clean design means it doesn’t need to be hidden away in a drawer when not in use. The only limitation is that it can only charge up to eight batteries at a time, which may not be enough for users with heavy battery usage. That said, at around US$30, the XTAR L8 offers good value for money for anyone looking for a tidy, easy-to-use AA and AAA battery charger that looks good on a desk.
