Luxa2 EnerG Slim 10,000mAh Power Bank: Closer Look
The Luxa2 EnerG Slim 10,000mAh Power Bank comes in a small black box with a clear window on the front that lets a potential buyer see the unit and get a understanding of its size. From the purely marketing standpoint, Luxa2 has hit all the marks in explaining what the device is and its use to potential customers.
The back of the box provides more details about the power bank. Among the listed details, we can see the whopping 10,000mAh capacity using a Li-Polymer battery. The approximate weight and size is 136 x 63 x 15.8 mm size, and the 222g, which isn't much heavier than a iPhone 6 Plus (175g) or Samsung Galaxy 5s (145g). Listed on the back gives a estimate of how many charges you can get per the major devices. Presumably the calculation is based on simple math, which is just dividing the battery complicity with the device in question by 10,000. However even with 90% conversion rate, the number isn't anywhere near the same. The official number around 2.3 times for my phone according to the box. While I am using the Samsung Galaxy 5s, which has a fairly large battery, this power bank has it covered and even larger devices like a iPad won't have any problems getting a full charge at least once.
Upon opening the package up, the power bank sat on a plastic tray with a USB charging cord. Below the tray itself was a quick start guide explaining what the device does and how to properly use it. Now, it isn't hard to understand how to charge a phone through a USB port. The difference is that with the introduction of USB 3.0, output voltages has increased, which is great news for larger batteries and quick charge times. The downside of this is that on some newer devices, they will not charge on the older USB 2.0 port as the power requirements is higher than what the port can provide. A good example of this is my Sony PS Vita, which until this power bank came out, would only charged from a house power outlet. Having a quick start guide gives a good indication of what should be charged with the 5V2a port versus the older one.
The power bank itself is of a simple design that has one function; to charge devices. To that effect, a black plastic case with a battery inside is all that is necessary. On the lower front is the Luxa2 brand name, while to the top it has an easy to read battery indicator. On the back is the charging ports neatly arranged across the top. The power bank itself isn't much larger than an iPhone 6 Plus or the Samsung Galaxy 5s. It can fit inside a jean or jacket pocket. I had no problem carrying it around for a few weeks while testing it.
To recap what was explained above, the power bank has two USB charging ports. The first port on the left is 5V1A, which is below the Battery Charging specifications under the USB 2.0 standard of 1.5A. The second port is 5V2.4A, which is above the USB 3.0 voltage regulations of 1.8A. This is great news for devices that may not like the extra voltage for backwards compatibility reasons. Also having a second port for higher output allows anything that can take advantage of it to be charged faster than through a normal USB port. Many of those wall outlet adapters are often around 2.4A and you can find out for yourself by looking at the label.
The front of the power bank includes a power level indicator, when pressed, displays the power reserve via blue lights. Each light indicates how much juice is left, with four being "Full" and one light blinking is less than 5%. If you want a quick estimate, just press the button next to the lights and it will light up accordingly. While charging, the lights will blink depending on how charged it is. This allows for easy estimates, but generally the recharge time is around seven hours, as the input is only 5V2A. The device itself has an auto power off, so when it's fully charged or not in use, it will automatically turn off to avoid wasting power.
