The UZI Micro Electric features 150 FPS full auto action, powered by an 8.4V battery (Battery and charger included). Metal barrel, and a 250 rd drop-free magazine round out the features on this legendary UZI replica.
I opened up the battery pack/magazine, it's 4.8V 700mAh and the charger power supply says 4.8V as well. The pellets get stuck once in a while. I didn't expect much though, for the price, it's an ok, fun shooter.
