Lumsing White Ultrathin 3.0 Bluetooth Keyboard Wireless Bluetooth Keyboard

Lumsing's ipad bluetooth keyboard measures 5.11 x 9.5 x 0.18 inches (130 x 240 x 3 mm). For comparison, the Samsung Galaxy Tab 3 8-inch is 4.87 x 8.26 x 0.29 inches. This keyboard will have a slightly larger footprint than the average 8-inch tablet, but it's still very small. If Lumsing shrank the footprint any more, they'd also have to shrink the keys – a sacrifice that would impact productivity.

Not only is the Lumsing keyboard very thin, it's also fairly light. It weighs 6.7 ounces (0.19kg), just over half that of the 11.07 oz Galaxy Tab 3 and 11.2 oz Tegra Note.

Charging and battery life

The Lumsing keyboard charges via micro-USB. A charging cable is included in the package, but users will have to supply their own USB power source in order to use it. Not a big deal, especially given the keyboard's price. The Micro-USB port sits on the back right side of the keyboard, near the power switch and LED.

Charging the keyboard takes up to two hours. While it charges, the Charge LED will glow red. Once the light goes out, the keyboard is fully charged. The battery has a capacity of 280mA. That doesn't sound like a lot, but Lumsing promises 100-140 hours of uninterrupted use. The Charge light starts to blink when power runs low.

Although the iphone bluetooth keyboard has an Off/On switch, it also offers a power saving mode. This sleep mode kicks in automatically after 15 minutes of idle time. To wake it back up, press any key and wait three seconds. Sleep mode is handy for folks like me with a propensity for forgetting to switch accessories off.
