Average Reviews:
(More customer reviews)This product is a basic battery, and an AC to Dual-USB charger. It does all this very well. It charges itself, and also charges up to two USB devices, and throws in a decent and very convenient LED flashlight. The case is rubberized, and feels rugged and durable. This should lead me to give it a good review, but I can't.
The use of a product like this is often for people on the go, like me. The battery in the unit is useful for giving a quick powerup for my mobile phone, or bluetooth headset, or any other USB charged device. So, I often throw this portable battery into my gear bag, or jacket pocket. The size is good for this too. The problem? The 'Power' button. The button is higher than any other piece of the case, which means that just about anything can and will hit it, turning the device on.
No worries, if a device (like my mobile phone) isn't plugged into it when it accidentally gets switched on, it shouldn't drain right? Well, normally, you'd think so. The power button cycles between 3 functions; FlashLight and Charge, Flashlight Only, and Charge Only. Remember that really useful flashlight? Guess what comes on first. Yup, the flashlight. That means that the light will be on until the unit drains completely. I have pulled the charger out of my bag on numerous times, only to find that it was drained dead. Useful, really useful.
For the product designers: The features on this are excellent. The power button needs to be fixed though. There are a couple of ways to do this. The first would be to just remove the LED light function, but that's really useful and a great little bonus. The other would be to simply add a raised bezel around the button, which would protect it from getting pressed so easily. This would require one to press down into the bezel to activate it. This would not completely eliminate the problem, but might bring it down to an acceptable level. Another option is to add a press and hold option, but that adds a smidge of cost. The bezel could be added with little to no cost impact. (Yes, I design products like this and understand the cost impacts and tradeoffs needed).
