The Stafix X18i unigizer is now available in Africa. This new addition to the X range of energisers which are able to run off either a 12V rechargeable battery or mains power source replaces the discontinued B18 energiser as the most powerful battery energiser available. It has an output energy of 18 Joules which is slightly more than the 15 Joules of the Stafix X15i and Gallagher MBX 2500. As with the other energisers in this range, the X18i features a backlit LCD voltage display, which, shows the output voltage, battery voltage and earth voltage. Probably its greatest advantage over the B18 however is its lower power consumption. Using a little more than half the power of the B18, together with the microprocessor which adjusts the output energy depending on the battery condition, this energy efficient unit is ideal for solar installations. The X18i also has a number of settings and pulse speeds which can be selected to further increase its energy efficiency. Pricing of the X18i is considerably less than that of its predecessors which will no doubt make this the energiser of choice for most agricultural and wildlife applications in Africa.
