#1 Anker PowerCore 2100
The Anker PowerCore is a great value for money. It’s not cheap, but it’s a great portable charger. This means that you get faster charging times (both iPhone 8 Plus & Galaxy S8), a higher capacity (charges the Galaxy S8 almost three times per charge), and the fastest charging times (Galaxy S8).
#2 Anker PowerCore 10000
The PowerCore 10000, one of the most compact chargers, packs enough juice to charge two smartphones and then some. Although it didn’t charge our phones as fast (the 20100-mAh Anker EnergyCore 20100), the 1000’s slower speed made it easier to use. Its portability and high mAh capacity make it the best portable charger.
#3 Belkin Pocket Power 5K Power Bank
Belkin’s Pocket Power 5K Power Bank ($29.99) is an inexpensive and durable portable charger. It has a 5,000mAh battery that can be easily carried in your pocket or bag. There is also a single USB A port that can quickly charge your phone at 5V 2.4 Amps. The best part is that Belkin offers a $2,500 warranty on connected equipment in the event your phone is damaged while charging via the battery packs.
#4 iMuto Portable Charger X6Pro
The iMuto Portable Charger X6 Pro boasts a massive 30,000mAh capacity for a reasonable price, along with numerous ports and fast charging support. It weighs 1.5 pounds and is one of the most powerful battery packs we have ever seen.
#5 Mophie Charge Force Powerstation
The Mophie Charge Force Powerstation can wirelessly charge your supported phones and tablets. The built-in Qi charging technology makes it more expensive than other 10,000mAh batteries. Cables are not required if your device supports it.
#6 Jackery Bolt
The Bolt was a winner in our testing. It charged 81 percent of our Galaxy S8 in one hour and 63 percent our iPhone 8 Plus in one hour. These are the fastest charging rates we tested. The Bolt’s 30 and 15 minute times are also outstanding. One thing to be aware of: The Bolt’s speed seemed to slow down once it was closer to a full charge. However, its time to complete a charge was longer than that of some of its competition. It also comes with integrated Lightning and micro USB charger cables, which are a nice perk that saves you from carrying your own.
