Review: RavPower Dynamo On-The-Go Power Bank
While biking home from my girlfriend's place one recent night, I managed to get myself lost in a rough part of town (don't ask how, I'm not sure myself). Ordinarily, I would have been able to simply pull out my phone and either call a cab or navigate back using the onboard GPS. There was just one problem, though - my phone was pretty much dead. I'd foolishly neglected to charge it for a day or two; as a result, it was pretty much toast.
Thankfully, I eventually managed to make my way home after making a call from a nearby Tim Horton's, though it's not an experience I'd care to repeat.
Many of you have had similar experiences, I'm sure - though perhaps not quite so harrowing as mine. At one point or another, we've all likely had our phones (or tablets) die on us, often at the worst possible time. Without immediate access to an outlet, what is there to do?
RavPower has a solution - the Dynamo-On-The-Go 7800mAh Power Bank. After spending a few days with the device, I must admit I'm rather impressed . It's capable of charging my phone's battery (I've a Sony Xperia L) with about the same speed as a wall outlet, and it can fully charge most devices several times over without needing to be topped up itself. It can also charge two separate devices at once, through the use of the 5V/1A and 5V/2A USB ports on the front.
It isn't just limited to charging up phones or tablets, either - pretty much anything from an iPod to a GPS to a portable game console can be plugged into the device, so long as you've the required cables for it.
It's quite simple to use, as well. After powering the bank up using the included wall jack (it doesn't take very long), just plug your phone, tablet, or MP3 player in, and press the power button on the top. That's pretty much it. If at any point you want to check how much juice your bank has left, simply press the button on the top and an LED indicator will light up.
Oh, it's also got a flashlight on the front, next to the USB ports. I'm not entirely sure why, but it's pretty handy. You can hold the power button down to turn it on or off.
Now, given that the whole point of this thing is to give you a means of keeping your devices charged when you're out and about, it's imperative that it be portable. RavPower's product is thus fairly compact, measuring in at 3.74 inches long, 2.28 inches wide and 0.75 inches thick. Even if you're carting a USB cable along with it, that's not really going to take up a whole lot of space - there's a pretty good chance it'll easily fit in your pocket along with your phone, if you don't have anywhere else to put it.
As you might imagine, a freelancer doesn't actually tend to get out of the house all that often. Theoretically, I should always have an outlet nearby with which I can charge up my device. You wouldn't be wrong in saying that I don't likely fall within the target demographic of this particular gadget.
Know what? I'm still finding it incredibly useful. I'm the sort of fellow who tends to pace when he's in the middle of a conversation. Understandably, that simply isn't something you can do when you're tethered to the wall. Plus, I do still go out every now and the; it's useful to have something like this when I'm over at a friends' place and there aren't any spare outlets.
Having a mobile device die on you is incredibly inconvenient, and you're not always going to be near an outlet or charging station. With the Dynamo-On-The-Go, that won't really matter so much. You can just plug your phone in, turn it on, and go about your business as usual.
The Dynamo-On-The-Go Power Bank comes with everything you see above. It'll run you at $79.99 on Amazon (currently on sale for $34.99). I'd say that's a pretty small price to pay, for the convenience it offers, wouldn't you?
