Until 1/21/16, Dell Home is offering the Dell VK70X 6 Cell 18000 mAh Power Companion for $109.99 with free shipping. You’ll see this excellent price when you checkout, and you’ll also see that they’ve added a Free $50 Promo eGift Card to use on their site in the future on a video game or maybe some other accessories. That makes it the best deal we’ve seen for this model at any time.
The idea behind this portable power supply is to bring the power with you. That means the six cell battery is filled by you, then used to power up your laptop, smartphone or tablet (2 at a time if you want in addition to the PC) all at once. It gives you a pair of USB ports you use to send power to your devices, so connecting is very easy. The included adapter is perfect for charging various types of devices.
