Plus, in our testing we found that the TN480U can also charge AAAA batteries (used to power some super-slim devices, such as laser pointers and styluses), even though this is not an advertised feature. DO NOT charge any other type of batteries inculuding, Ni-CD, NiMH and earlier versions of iPowerUS batteries in the iPowerMax Exclusive Charger. Devices with built-in batteries can be more convenient to charge, and they are certainly more commonplace. Easy to use, it can be connected to your mains, vehicle or PC though a micro-USB or DC input for on-the-go.

There is built in discharge protection as well as reverse polarity protection and the Solar Charger will not overcharge your battery. When plugged in, it blends in with its surroundings fairly well, especially if you have white walls. With a listed charge-rate range of 300–400 mA, it’s less than ideal for charging AA and AAA batteries (which need 1,000 mA and 500 mA, respectively, to charge optimally).Even when these ports were not in use, our batteries charged so slowly in testing as to make the charger impractical. Designed to cater to both business and consumer needs, this charger excels in functionality and innovation. Special note for Australia: We have been advised that parcels are currently expected to take 15-25 working days to arrive to Australia, depending on the location. Lights above the Panasonic Eneloop BQ-CC55’s four charging slots indicate whether each battery is dead, partly charged, or fully charged by turning red, yellow, or green, respectively. Higher end models will charge 4 AA batteries in as little as 15 mins, while more cost effective options have charge times between 1 - 4 hours.

This Ansmann Powerline 2 9V 6LR61 battery charger features individual cell monitoring and charging cycles for each slot. Instead of the TN456’s included proprietary charger, the XTAR charges over USB-C and comes with a compatible 18W USB wall charger and charging cable. However, it’s not a pick because it’s made of a flimsier plastic than the EBL 6201, and it has a less elegant, chunkier shape. We especially like that the BQ-CC55 has a fold-out plug, so it sits right on the wall outlet as it charges, and its notification lights correspond to the individual battery slots. Most devices work fine with either battery chemistry, as long as the battery is the correct size, but some devices (whether it’s a detachable camera flash or a child’s toy speedboat) may function better with the additional burst of voltage that a lithium rechargeable provides.And because speed of charger does matter, Duracell chargers are charging faster than the best-selling competitor worldwide*. Capacity: After fully charging each pair of batteries in their corresponding chargers, we stuck them into a Powerex Maha Advanced Battery Charger. The unit is maintenance free and will protect the battery against the discharge process that occurs naturally within a lead acid battery. It’s easy to use, has indicator lights over each battery slot, and has a good range of currents (225–1,800 mA) for efficient charging. The Powerex Maha MH-C808M has many of the same problems plaguing the other Powerex models we tested: It’s bulkier and has a less intuitive interface than comparable models from other brands.

Ideal for situations where a top up-charge is needed and where you need the assurance that the charge level is accurate and safe to minimise any possible risk of battery damage.This charger could hardly be easier to use: You simply insert up to four AA or AAA rechargeable batteries and leave them charging for an hour or so. It’s super reliable and still in perfect condition, though admittedly it stays in one spot [in] an office no one else really comes into,” he said. It also has a worse interface, since its screen doesn’t show if the “condition” or “soft” charging options are turned on.
