Compact and convenient, this JOLT 4-N-1 is the perfect little lifesaver! This stun gun is the ultimate small self defense weapon with an 80M volt stun feature that can simultaneously work with the flashlight on as well. Not too many stun guns allow you to use both without having to turn one or the other off. This JOLT also has a 120dB panic alarm to deter possible attackers and to alert nearby people that you need help. One of the best parts of this stun gun is the fact that it has a built-in power bank that can charge any USB compatible device and bring it back to life. When the stun device is fully charged, it will recharge a smartphone up to 25% power. On top of that, it is small and easy to conceal and allows you to carry it on your keys or use the metal clip to securely attach it to your belt, pants, purse or pocket for handsfree carrying. It is also backed by a limited lifetime warranty.
