Watson AAC-836LBI-B Overview

This AA Lithium-Ion Battery Charger from Watson comes with eight rechargeable batteries in a convenient and portable eight-bay charging case. Each battery provides 3600mWh and 1.5 V for long-lasting and constant power throughout the discharge cycle and can be recharged up to 1200 times for sustainable and repeated use. Battery activation helps restart drained and unused batteries so they can be charged like normal.

Individual charging slots and LEDs for each battery keep your batteries organized and easily show the charging status of each battery. A powerful 20 W AC adapter offers USB-C and USB-A ports so you can charge the batteries and an additional electronic device like a smartphone at the same time. Protection circuits guard against short circuits and overheating, and there's an explosion-resistant design for worry-free charging and powering of devices. The IP67 rating shields the batteries from dust and water so you can use your electronics outdoors or in commercial settings, or so they can survive an accidental spill or rain.

Long Lasting
Each AA Li-ion battery provides 3600mWh of long-lasting power. Rechargeable Li-ion batteries are designed for high-drain devices like camera flashes and wireless microphones and transmitters. These AA batteries deliver a constant 1.5 V output voltage throughout the discharge cycle and can be recharged for up to 1200 charge cycles.
Topside Charging Status LEDs
Each independent channel has a topside charging status LED. Easily identify batteries that are charging and when they're ready to use, as well as batteries with errors.
Low-Voltage Activation
This charger offers low-voltage battery activation for those used AA Li-ion batteries that have been sitting in a drawer for a while and have no charge. Reactivation of a battery requires a wake-up pulse from the charger, which jump-starts the battery and resets it for normal charging.
Storage Case
The charging case is also a convenient way to store the batteries. Having a dedicated place to find, store, and charge the AA batteries saves you from digging through a drawer, and while traveling, you'll need only the case and charger for everything.
Power for All
A 20-watt adapter provides all the power and ports for charging. USB-C and USB-A ports make it easy to charge the batteries and your phone at the same time.
Safety Features
Protection circuits guard against short circuits and overheating caused by high voltages and currents. These circuits monitor the power and temperature of the charger and batteries for optimal charging and safety. There are additional protections with the IP67 rating and against battery explosions, allowing worry-free operation.

Watson AAC-836LBI-B Reviews

not great

a cool and different system for charging but the batteries seem to lack power for the flash. Worked great for about a half hour and then took a really long recharge time. I will end up going back to enloop or just ditch AA rechargeables alltogether!

The only AA rechargeable battery kit you need

This Watson AA battery kit has been a really great addition to my gear. I go through a lot of AA batteries with things like wireless mics and accessories, so having a reliable rechargeable solution like this makes a big difference. The batteries themselves hold a solid charge and deliver consistent power, which is exactly what you want for high drain devices. One of my favorite parts of this kit is the charging case. Having everything contained in one place is incredibly convenient. I do not have to dig through drawers or keep track of loose batteries and chargers. I can just grab the case and go, which is perfect for travel or working on location. The individual charging slots and LED indicators also make it easy to see exactly what is charged and ready to use. I also like that the adapter/charger brick has both USB-C and USB-A ports. Being able to charge the batteries and another device like a phone at the same time is a really useful feature when outlets are limited. It just adds another level of flexibility to an already well thought out kit. Overall, this is a very practical and well-designed setup. It keeps everything organized, charges efficiently, and gives you dependable, long-lasting power when you need it. I’m very happy and impressed with this 8-bay charger [I have received this product in exchange for my honest review.]
