Dell Home offers its Dell 18,000mAh Power Companion, model no. PW7015L, bundled with a Slim Power Adapter and a $50 Dell eGift Card for $129.98 with free shipping. (The gift card will appear at checkout and be emailed to you within 10 to 20 days of shipping.) Assuming you'll use the gift card, that's the lowest total price we could find by $15 for just the power companion, although we saw it for $4 less without the power adapter three weeks ago. It features two USB ports and LED charging indicators. Deal ends December 21.
