It is the only Power kit that is a true all-in-one product. This 12000mAH compact battery pack is capable of charging hand held devices and laptops and is capable of powering 12V appliances that are outfitted with a 12V adaptor. Despite being so small, it has enough juice to jump start vehicles up to 60 times on a single charge. It supplies 500A peak current and can jump start the car up to 5.5L gas engine. What really sets our power kit apart from any other competition is that a 150PSI ready-out-of-the-box air compressor is included in the kit. It can inflate your car flat tire to full within 5 minutes. It can inflate your bike tire, sports balls, inflatable toys within seconds. That amount of power in a handheld device is almost unheard at such an affordable price point.
