I was provided with a free copy of this product for testing and my honest review.
The Good: Going camping? Pick this up first. This product by RAVPower is one of my favorite battery packs. Packing in 7800mAh of LG lithium-ion battery cell power, I can get right around 4 full charges into my Moto X. This external battery also doubles as a flashlight/lantern, which is perfect for camping! Adding on to this, the battery is also relatively portable, at 3.86 x 1.89 x 1.89 inches and weighing in at just around 7 ounces. You can squeeze up to 72 hours of continuous lighting out of this battery pack, which means you’ll never be left without light! The Duo is a triangular prism shape, and has a soft grip exterior feel to it.
On the bottom of the battery is some RAVPower branding, along with some information, such as: Model, 7,800mAh battery, 1.2 Amp charging input, and 1.2 Amp charging output. On two sides, near the bottom are two different ports; a USB port for charging other devices, and a micro-USB for charging the Duo. On the third side of the device is the power button along with four small battery indicator LEDs. To activate the lantern, simply hold down the power button for a couple of seconds. This can be done while the battery is collapsed (flashlight mode), or expanded (lantern mode). This battery features over charge protection and short circuit protection features.
The Bad: Camo design. This is a matter of opinion, but I personally do not like the camo design, and don’t understand why it’s there. Although brighter than other battery pack flashlights, I was expecting the light on this device to be a bit brighter, since it is advertised as a lantern as well as a battery pack. Also, it would be great if the battery had a faster charging input and output.
Cool Features: 7,800mAh battery, flashlight/lantern, over charge protection, short circuit protection.
In The Box: The box itself is a fairly simple design. Inside, the battery is packed in snug with a USB cable, instruction manual, and carabiner/lantern clip.
The Verdict: Overall, this really is a nice product. It offers high performance and power with portability and practicality. This is one of my favorite battery packs, and a must have for any avid camper, heavy electronics user, or anyone looking to extend the battery life of their device.
