Smartphones and laptops are lifelines and it can be a major inconvenience if they die at the wrong time, which is why portable batteries are so popular. When shopping for a portable battery, it's important to get one that has a high battery capacity, but is also lightweight enough to tote around.

Consider picking up the Yukuma 10,000mAh Battery, which delivers a full charge in just 30 minutes, a rate that's nearly ten times faster than typical battery packs. With two USB ports, you can charge more than one device simultaneously, and the pack's high capacity ensures you'll be able to recharge any device multiple times while on the go.

This portable battery normally retails for $120, but Daily Beast readers can get it on sale for $69.99, a 41% discount.
