Charging USB Devices With AA Batteries

In this article, we will share with you some devices that use AA batteries to charge USB-powered small electronics. These devices provide a convenient way to stretch the time between wall outlet recharges.

Some are advertised to work with any type of AA battery, giving you lots of options if you are in a pinch as well as permitting you to use resource-saving rechargeables. Here are some we found:

QuickerTek claims its Apple Juicz Little Black Box is the first charger of its kind that will accept any type of AA battery, including alkaline, nickel-metal hydride (NiMH), nickel-zinc (NiZn), and carbon. As long as each of the four batteries installed is of the same type and brand, this unit’s internal circuitry will adjust voltage appropriately. QuickerTek advertises compatibility with most any USB-powered device, including iPod, iPhone, and iPad. The Apple Juicz Little Black Box measures 3.16” L x 2.46” W x 0.76” D and weighs 1.6 ounces without batteries. There is an on/off switch and a single female USB port. Batteries are not included, and the manufacturer recommends NiZn batteries for best performance.

Neewer Emergency Charger with Flashlight

The Neewer Emergency Charger with Flashlight draws a surprising number of reviews on Amazon; over 40 customers weigh in to give the black-colored model an average of 3½ out of 5 stars, and about 10 people give the white-colored version an average of 4 stars. This charger accepts two AA batteries; though the manufacturer does not specify which types are appropriate, customers seem to have success with both rechargeables and non-rechargeables. On the edge of this unit you’ll find an on/off/flashlight switch, on its face there is an LED charge indicator, and on the end is the female USB port and LED flashlight. Most reviewers like this charger, citing its high value, slim profile, and wide charging compatibility. But this charger also draws negative feedback for running hot and inefficiently. Neewer claims compatibility with just about all USB-powered devices, including iPhones. Batteries are not included.

Amazon sells the Neewer Emergency Charger with Flashlight in black or white, both for around $5.

Zap RX-4 Recharge-It-All

The Zap RX-4 Recharge-It-All accepts (and includes) four AA batteries. Eight Amazon reviewers give it an average rating of 4 stars. Customers like the flexibility of this device—it accepts alkaline and rechargeable batteries, includes a USB cable with adapters for different mobile phones, and it can be plugged into a wall outlet to recharge the batteries it holds. It has a four-light LED battery-life indicator and comes with a carrying case. The biggest complaint is about the included rechargeable batteries; customers find they aren’t nearly as good as most rechargeables on the market today. Though the manufacturer claims wide compatibility, some customers report the RX-4 Recharge-It-All will not charge their devices.

Purchase the Zap RX-4 Recharge-It-All for about $18 on Amazon.

The Voxred Turbo Charge comes in a variety of packages, all with different sets of charging cables. We recommend the TBB850 or TBM1050 packages; each comes with a mini-USB adapter and the TBB850 also includes a micro-USB adapter. You can order additional adapters through the manufacturer. The Turbo Charge accepts two AA batteries (rechargeable or non-rechargeable), and two AAs are included. It measures 3” L x 1.5” W x 0.75”D and weighs 2.5 ounces with batteries installed. There is a three-level LED battery-life indicator and an on/off/flashlight switch (the flashlight is two white LEDs on the end). CNET gave the Turbo Charge 4 out of 5 stars in 2007. Customers have been a little less enthusiastic; their chief complaint is that the batteries are depleted well before the advertised two to three full charges for portable electronic devices.

Both the Voxred Turbo Charge TBB850 and TBM1050 are for sale on Amazon for around $18.
