I-Up 5400 Review
This external battery has more than two-and-a-half times the storage capacity of other low-cost mobile device chargers and gets positive reviews from users.
The I-Up 5400 offers as much battery power as many mobile device chargers with far higher price tags. That's the major selling point, according to I-Up 5400 reviews, which report that the I-Up's 5,400 mAh battery can charge smartphones up to four times without itself needing a recharge. The many adapters, including a micro-USB tip, that come with the I-Up 5400 make it compatible with Nokia, Motorola, Sony Ericsson, Sony PSP, and Samsung devices. In one I-Up 5400 review on YouTube, the user reports that the unit charged every device he tried, up to and including the camera he used to make the video.
Many users posting I-Up 5400 reviews on Amazon come off as evangelists for this low-cost mobile device charger, sharing stories of how it saves them whenever they're away from an electrical outlet. Users' main gripe with the I-Up 5400 is that it can't be recharged via a computer's USB port; the only option is to plug it into the wall. We read some minor grousing in I-Up 5400 reviews from users who worry they'll have a hard time keeping track of all the parts, and another review on YouTube says it would be nice if the I-Up 5400 came with a bag for the adapters.
Five indicator lights tell you fairly precisely how much battery is left, while another light turns from red to green when a device is all charged up. An additional, seemingly superfluous feature is an illuminating LED light, which we suppose would make the I-Up 5400 doubly useful during a power outage. This bargain mobile device charger also includes built-in temperature and overcharge protection.
You get a lot of external battery for your money with the I-Up 5400 -- more than two times the capacity of the average mobile device charger available at the lower end of the price range. If you've got big-time charging needs, this model could be the one for you.
