I got myself this battery support, because it is everywhere to shop. Thanks to the USB mini port. Another reason: The voltage is continuously adjustable from 3.0 to 5.5 volts, just the wattage 2.2 to 20 watts. Also important, he displays the Ohms of screwed evaporator. Ideal for Selbstwickler. A protection circuit is the battery carrier also. Should you in the low ohmic range come Happened "Nothing". The device protects you and yourself. In a normal battery (ego), the electronics would be destroyed. The low ohmic range below 1.0 ohms is not for beginners, but only for specialists with experience and special batteries. With this device you can operate all the evaporator, so there are on the market. I am enthusiastic about the device. And send it looks. Had I forgotten. During charging, you can continue to evaporate safely.
