Review Summary:

PROS: Provides 14000mAh battery. Reliable performance. Affordable. CONS: Sudden and large price drop. Take 12-13hrs to be fully charged. Small annoyances.

Most of us can greatly benefit from an external battery pack, especially if you’re using one of the newest generation iOS devices. These days, all iOS devices are very power-hungry, and even though new devices can hold plenty of power, they start to age and potential of maximum available power starts decreasing. So if you’re using an iPad along with your iPhone throughout the day, it may be a good idea to have some kind of battery pack at your home or in your office, and especially if you’re taking a trip.

Today you can find some high-capacitive batteries at affordable prices, so there’s a huge choice available. We already reviewed some external battery packs which are iOS-compatible, like HyperJuice 2, Gum Max Duo, and Mophie’s Juice Pack Powerstation – to name just a few. Today we are going to take a look at one of the biggest high-capacitive batteries currently on the market, named RAVPower Dynamo, which brings astonishing 14000mAh battery. It’s priced at $130, which sounds like a good deal, so let’s see how this battery pack performs and if you should trust the official statements.

RAVPower Dynamo 1

Size of a battery corresponds to its capacity, so it’s no wonder that RAVPower Dynamo is a large product. It isn’t much bigger or bulkier that those 10000-12000mAh batteries, which are currently very popular. You can purchase it in white or black edition, corresponding to your iOS device.

In the packaging you’ll find the RAVPower Dynamo battery, along with two coiled USB cables with several extensions for different kinds of inputs. You’ll get two 30-pin connectors, but if you’ve got the newest generation iOS device you’ll need to supply your own Lightning cable.

The RAVPower Dynamo comes with a fairly traditional design. It comes as a solid block, with two USB ports on one side. The ports are 1-Amp and 2-Amp output, so you can use one with your phone and the other one with your tablet. There’s also standard charging port. On the top you can find the power button, which doubles as trigger for checking the remaining power inside. Simply press it for a few seconds, and the large LED light will signalize how much juice there’s left. This blue light bar illuminates in four independent segments, so it shows in quarters how much power there’s left.

RAVPower Dynamo 2

When it comes to performance, it’s fairly standard for a typical power pack. This means that it’s fully usable and offers promised 14000mAh, but I was disappointed with some aspects. For example, the provided 2-Amp which can be used with the iPad 3 and 4 could have been a bit faster. Also, the input charging port come as 1-Amp, so it will take approximately 12 to 13 hours for this battery to be fully charged.

The one thing I am concerned about is that the initial price for this product was $130, and now you can find it at some online resellers at only $50. It comes from a fairly new and unknown manufacturer, so even though I didn’t have any problems with it, I am not sure if I should trust it in the long term.
