You put a lot at risk by leaving the house without a portable charger or battery pack. Once your smartphone dies, you can't call, text, or tweet, rendering you disconnected from friends and family. And if you're taking any sort of transit home, do you really want to go without your songs and podcasts, and endure listening to the conversations of others? One charger can even deliver enough energy to satisfy the power-hungry Nintendo Switch, which charges over USB Type-C, while another -- that resembles a golf club -- doubles as a Bluetooth speaker.
Note: the milliampere-hour (mAh) rating for each device indicates how much juice it stores, and, generally, speaking bigger is better.
If your phone keeps hitting the red battery icon before you get home, and you have a bare minimum of space to carry anything else, check out this hand-heldsize power source. The 6,000-mAh Jackery Bar Premium may be small (measuring 3.8-inches long and 0.9-inches thick), but it should offer enough power to refuel an iPhone for up to 3 cycles.
The id America LED Portable Charger's three lights do double-duty as a lamp. Plus, the magnets built into its back let you mount it on any surface. Late-night snackers will appreciate the option to mount this 5,200-mAh charger on their fridge. Or you can even mount it on your bicycle handles for a late-night ride.
For those who opt for metallic tones across their accessories, the pint-sized Letv Super Powerbank may the best bet, as it fits right into your look. Available in gold, silver and black, this 13,400 mAh charger offers two USB ports so you can charge two devices at once, saving your device and a friend's from a power outage at the same time.
The RAVPower Power Bank can charge 4.5 iPhone 7 phones before dying. The 12,000-mAh power source weighs a mere 8.5 ounces, so it won't drag you or our bag down. Plus, its dual 2A inputs means you can charge two devices at once, as well as fill a device in as short as 6 hours (twice as fast as 1A chargers).
When you're on the go and your phone needs a charge, you'll probably want it to fill up as fast as possible. Anker's PowerCore Speed 10000 portable charger will save you time in those moments, as it uses Qualcomm Quick Charge 3.0 technology along with the company's own proprietary technique to refuel your devices as fast as possible. The 10,000 mAh power source offers enough juice to power up at least two iPhones or Galaxy phones.
One of the best portable power options for Samsung Galaxy device owners, the Fast Charge Battery Pack is supposed to bring compatible devices from dead to 50 percent in about 30 minutes. Its 5,200-mAh capacity is more than enough to fill a Galaxy S8+ (3,500-mAh) or S8 (3,000-mAh) and still leave some juice for a future refueling. The battery pack features pass-through charging, so you can charge the pack and the connected device at the same time from the same source.
Portable power sources are supposed to reduce your number of nuisances, but traveling with one often requires you to keep a charging cable with you, adding clutter to your bag. The 6,600-mAh Mixit Power RockStar helpfully stows its micro USB charging cable internally. It features two USB ports that can be used to simultaneously charge two smartphones.
