On my model, the aluminum finish gives a certain cachet to the battery. Especially she goes everywhere with its mini format. And unlike other batteries that have developed a secondary function of emergency lamp, it is more like a real flashlight with a relatively powerful lighting.
Its operation is simple since it has two ports, one for charging the device and another used to recharge the battery. A knob is also present to light the lamp. Click on it twice for the trigger twice to turn it off. Note that the button is really small and that more easily with a fingernail clicked with a finger. This is both good because it avoids the turn without meaning in a bag but it's a bit complicated to turn it on if it is used by flashlight in the dark, for example. Lorsquon click once, the button glows green. When you load a device, battery flashes green while it via its button flashes red when the battery is being loaded. The charge is issued only against 1A and may be slower than regular charger if the smartphone is recent. His power load will not make miracles but not enough to fully charge all smartphones 1 times and ensure more micro-refills (when the battery approaches 50% for example). It is against insufficient for a tablet that will moreover a long time to load (most chargers 1.5A).
In the end, we take a small battery that holds up and can also be used as flashlight, than to troubleshoot. This is a very good compromise especially as the price (12.99 when I write this) is very competitive. We just regretted the limited load 1A.
Pros: - minimalist gray aluminum design (for my model) - Format and lightweight that fits everywhere - Lamp function really successful pocket (with a strap, we take a real flashlight)
Cons: - load capacity limited to 1A
