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 Apple Juicz Little Black Box
- Neewer Emergency Charger with Flashlight
- Zap RX-4 Recharge-It-All
- Energizer Energi To Go CEL2MUSB
- Voxred Turbo Charge
QuickerTek Apple Juicz Little Black Box
QuickerTek claims itsApple 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.
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.
Energizer Energi To Go CEL2MUSB
Energizer’s Energi To Go CEL2MUSB charger operates on two AA batteries. This charger includes two Energizer Ultimate Lithium AAs, but customers say rechargeables also work. Customers also say the Energi To Go CEL2MUSB performs as advertised, working with a wide range of USB-powered devices and remaining reliable long after their purchase. There are some complaints about the battery door being difficult to work with and some reviewers found this charger was not compatible with their phones after they bought it, but overall the feedback is positive. The Energi To Go CEL2MUSB comes with adapter for mini- and micro-USB connections. The company states this charger is not compatible with iPhone or HTC Android.
Voxred Turbo Charge
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.
