Excellent battery carrier in box form

Pro:
1) You can lock the set values, so you do not accidentally changed the wait.
2) The box feels very valuable to, is quite difficult, although it is made of aluminum, and inside a DNA is built 30 chip, which oddly enough can output 50 W! There are original of HanaModz no DNA chip 30 which outputs 50 watts. Furthermore, you have to press the fire button once to wake the device from sleep, Derst then fired.
Thus, it could be here a clone of that box. If so, it's a really brilliant copy, perhaps better than the original DNA 30W Box of HanaModz.

In the box can be charged a battery, I recommend
Panasonic NCR 18650B 3400 mAh Li-ion

Cons:
1) The battery is very, very difficult to get out and in, to change you have to unscrew the 2 Phillips head screws (therefore I think of a remodeling of the lid by means of magnets).
2) The unit comes from England and delivery will take about 9 days

Conclusion:
This box can be anyone, even beginners, who have the right battery (Panasonic NCR 18650B 3400 mAh Li-Ion)
