Value -
Value is another very subjective topic. What is expensive to some might be a deal to others. You can look at this topic in multiple ways. One is raw price and the other is what you get for the money. Each is accurate and both are correct ways to look at price/value. We tend to look at features, performance and real-property when we discuss value. However, we also take into account the raw cash cost of the item.  The Ravpower RP-PB04 goes for about $40 on the internet with the lowest price we saw at about $36. This is a solid price for a product that will let you recharge your phone or tablet multiple times on the go. There are a few other competitors out there with similar prices so the RP-PB04 will have some competition.

Conclusion -
The mobile power market is still a small one, but as the mobile market grows the need for this type of product will grow as well. Right now we have tablets, phones, watches, headsets, and more that rely on power every few days (in some cases every few hours). This need will grow over the next few years and will make the demand for devices like the Ravpower PR-PB04 grow. The Ravpower line up (and the RP-PB04 in particular) has some excellent performance to back up their place in the market. With its weight, capacity, and fairly slim design it will be replacing our older backup power source when we go on the road.
