This will require the use of their smartphone or their tablet. Note that you can access the type of battery 18,650 by unscrewing the lamp. We can also charge it with a charger suitable if this type of battery you have (for UltraFire lamp). It should also unscrew the compartment to remove a small protection before use. The lamp measures 17.2 cm long with a diameter of 3 cm and a weight of 151.6 grams. The battery is 2400 mAh and delivers an output of 300 lumens. A wrist strap confirms that this is a lamp before a backup battery.

The lamp is very powerful and makes immediately think of a UltraFire torch. It can be set via two modes plus a function to blink. We can also extend the high part to diffuse light in a wider circle, if not downright bring out a little tube which is ideal in a tent for example (see video).
This lamp can also be used as battery backup since with its load of 2,400 mAh, it can recharge once most modern smartphones. By cons, it therefore delivers qu'1A and recharge more slowly greediest devices like Apple's.

This lamp Battery 2 in 1 is designed primarily as a lamp and therefore excels in this area. It acts as a mini-troche UltraFire which can easily adjust the precision and the desired intensity. And it can also occasionally serve as a backup charger.
