Smartphone batteries don’t really do their high-tech phones any justice. It seems as if the technology for smartphones has reached such a high level, that batteries simply can’t keep up. That’s why we have smartphones that simply run out of juice after a few hours of extensive usage.

The reason for this is clear, the features on our phones are simply too demanding in terms of power usage. Cameras, high definition screens, WiFi and other features simply drain the battery at such a speed that even the most expensive phones hold only a couple of days before the need for recharging arises.

Although we might think that the solution for this problem is the invention of better batteries that could hold more power, we’ve reached such a high level of battery technology that there is simply nowhere to go.

Portable chargers have become the standard in terms of providing your smartphone or tablet with a longer battery life. The way portable chargers have changed the landscape of telecommunication technology is indicative of the way we use them.

The more features we want and/or need on our phones and tablets, the more battery will be drained in a shorter amount of time. Since we don’t have the possibility to make the batteries bigger due to design reasons of our modern phones, there had to be a way to get batteries to last longer without changing them mid-use.

Portable chargers were invented to accomplish exactly that, and now we’re going to take a look at one portable charger in particular, the “External Battery RAVPower 16750mAh Portable Charger” model.

The “External Battery RAVPower 16750mAh Portable Charger” model is an incredible product that promises a lot of things and keeps almost every last one of those promises. The way it incorporates the technology of charging in an overall nicely looking product is astonishing on its own.

However, the real kicker is the way it handles the performance aspect of charging your devices. With an incredible capacity and undeniably good price to value ratio, this portable charger is truly one of the best portable chargers in its price range and overall category. To prove that, we conducted some comparisons with other similar products of the approximately same price range:


The first model we compared it to was the “iMuto 20000mAh Compact Portable Charger”. This portable charger is amazing in what it does in terms of capacity and simple durability. The biggest complaint we have, however, is the fact that although it’s a bit more expensive than our reviewed portable charger, it delivers fairly same results.

This means that paying for the iMuto model may seem like a move that’ll get you more performance, but what you’re really getting is the same performance as with the RAVPower portable charger only more expensive.

Another model that can be compared to the RAVPower model is the “Portable Charger, Spigen® [F710D DUAL]”. This model is extremely powerful and a bit cheaper than the previous two models. However, you can see that right away once you hold it in your hands. The performance may be the same, but the cheap feel you get from this model simply lets you question how durable the device is over a longer period of time.


The “External Battery RAVPower 16750mAh Portable Charger” model is an incredible device that lets you get the best possible performance in terms of portable chargers.

The technology is the latest in the field, while the price is simply incredible. You get a lot more than you pay for, and that’s always a good thing with portable chargers. Even when compared to slightly more expensive items, this portable charger is miles ahead, although it costs only a fraction of the price.

So, if you’re looking for a reliable portable charger that gets a lot of things right and doesn’t cost much, this is the product for you.
