Watson AA-U4CB overview

  • 1Description

The Watson 4-Bay USB Charger and Portable Power Pack charges 2 or 4 AA or AAA NiMH batteries at a time, and is capable of charging cells of both sizes simultaneously. Charging time ranges from 1.9-2.2 hr for AAAs and 4.3-6.0 hr for AAs. The charger/power pack features a micro-USB input port for charging batteries, as well as a USB 2.0 output with a blue indicator light for charging mobile devices when 4 AA or AAA batteries are installed. When charging mobile devices, the unit can accept either rechargeable or non-rechargeable batteries. LED indicators show charging and output status.

Reverse Polarity Protection safeguards the charger and your batteries against damage when batteries are installed improperly. The integrated AAA chamber adapter simply slides down to reduce the size of the battery slot, allowing you to insert a AAA instead of a AA. A circular hole in the back of the device makes battery removal easy by enabling you to pop the cells out with your fingers. A USB-to-micro-USB cable is included.

    Watson AA-U4CB reviews

    4-Bay USB Charger and Portable Power Pack for AA and AAA NiMH Batteries is rated 3.7 out of 5 by 7.
    Rated 4 out of 5 by from Reasonable price, but may limit battery life After receiving the Watson 4-Bay USB Charger and doing some additional reading I decided to return it to B&H unopened. Instead I will be ordering a smart charger which measures the voltage among other indicators, to determine when the battery is fully charged. Of choices I feel that perhaps the La Crosse BC-500 Alpha Battery Charger B&H # LABC500 MFR # BC500 might better suit our needs while protecting our investment in batteries by way of a more sophisticated overcharge detection.

    Rated 1 out of 5 by from Don't bother with this charger... Tried to charge my new eneloops off and on for 3 days with this. The lights never both turned green. Put the batteries in my old Duracell charger, and they were NOT charged. Don't know if mine was a lemon, or this is just a bad product. B&H Returned my purchase price right away when I called them.

    Rated 4 out of 5 by from No wall plug, no problem. :) When you're on the road and no access to wall-plugs to charge your AA/AAA batteries, this little device lets you use a portable power station to recharge your batteries. OR, when you have fully charged batteries with you, you can reverse the role and use THIS device as a portable power station to charge external devices from it. Very smart, very simple, very useful! Not sure about reliability though, since it feels a bit flimsy. But still, it's a 4 Star ratings easily! :)

    Rated 3 out of 5 by from Works, but possibly fragile Works as advertised both for charging AA and AAA batteries and for serving as a power bank to charge other devices, such as an iPhone. Construction seems a bit flimsy. I haven't had it long enough to gauge durability.

    Rated 5 out of 5 by from Affordable price and perfect for the job This charger is very durable and charges both the AA & AAA batteries at the same time. I really like it.
