The MyCharge HubMini 3000mAh portable charger combines impressive technology with a convenient size for on-the-go auxiliary power.
This handgrip-style unit has two built-in charging cables -- microUSB cable and Apple Lightning, so you don't need additional cabling.
You can use them for 20+ additional hours of talk time, or even charge two smartphones simultaneously. (There's also a microUSB port for recharging, but no USB power port for other cables.)
The HubMini is built rugged, wrapped in anodized aluminum, and is still under 3 1/2 x 1 1/2 x 1 inches, and less than 3 ounces.
MyCharge piles on the technology for its Hub line of chargers with integrated cables, from the HubMini up to the HubUltra for 90 hours of power for phones and tablets.
These include faster charging (up to 30% faster than the Apple charger), faster recharging (as much as 4X faster than competitor's chargers), and smart device detection and circuit protection. These also can simultaneously recharge the battery while charging your device.
In addition, they retain up to 60% of a full charge for up to one year, which means you can throw them in a bag and not obsess about needing to recharge. They also will be pre-charged if you buy them off the shelf -- ready to power you up right away.
The MyCharge HubMini is available for around $69. It's easy to carry, and provides a quick boost for a flagging smartphone -- or two.
