Don&8217;t confuse Neostar&8217;s sleek new 5-bar power bank with any ordinary emergency charger. It will restart your car, van or boat even if your battery is completely flat &8211; simply attach the supplied jump leads. It&8217;s also powerful enough to charge laptops as well as sat navs, tablets, phones & e-readers. The integral LED flashlight is a useful third function, which can be used for close work or switched to strobe or SOS for emergencies. Don&8217;t worry about battery drain either, because unlike other power banks this model will holds its charge for 6 to 12 months. You can recharge it from the mains or your car &8211; mains & 12V chargers included.
