The Best Portable Battery Packs of 2021

Need a battery that has everything but the kitchen sink? That would be the wonderfully named Fuse Chicken Universal. This compact (3.1 by 3.1 by 1.1-inch) device contains a power supply with USB-A and USB-C outputs, awireless charging padand a 6,700 mAh battery for recharging on-the-go. Oh, and don’t forget the included international plug adapters for charging in the US, UK, Europe Union, and Australia. The 6,700 mAh battery has enough oomph to recharge an 11-inch iPad Pro to about 80% or recharge an iPhone XS twice, so it should be able to get you through all but the longest airplane flights. Plus, when you arrive you can plug it in and charge it up again, so that’s one less thing to carry. It supports the Power Delivery (PD) standard, which means it can up the voltage to deliver more juice, delivering 18 Watts (at 12 Volts, 1.5 Amps) through the USB-C port.

Putting all of this aside, the Fuse Chicken Universal is more expensive than many other batteries of the same capacity.

最新一代的iphone有苹果的杂志afe charging technology baked into them: each phone is armed with a ring of magnets that allow a wide array of accessories to snap into place on the backside of the smartphone. Anker’s PowerCore Magnetic 5K is also Magsafe-compatible, which means you can hold it near the back of an iPhone 12 or later generation Apple smartphone and it will snap firmly into place and deliver 15 Watts of power to the phone via its wireless charging coils. During testing, we found that the battery’s connection to the back of our iPhone was firm, but not so firm that it couldn’t be removed when the time came to do so.

Having tested the Magnetic 5K with a pair of Samsung handsets, we were pleased to find that it was compatible with non-Apple devices. That said, while charging these devices wasn’t an issue, the battery would not lock onto the back of them as it did with our iPhone 12. It’s also worth noting that, when this battery is used with a non-Apple device, it doesn't charge as quickly, as it automatically switches over to the 7.5 Watt Qi wireless charging standard. There's a single USB-C port on one edge, along with a button to turn the wireless charging on and five LEDs that show the charge level. Additionally, the Magnetic 5K’s single USB-C port can be used to charge other devices, although we found that it could only manage about 11 Watts of output power.

The Anker PowerCore 10000 favors simplicity over features: you get a 10,000 mAh battery, one USB-A output, one USB-C output and—that’s it. No built-in cables, no multiple outputs, no wireless charging, and no other fancy features. This battery has it where it counts, though, holding a hefty 10,000 mAh of power. That’s an impressive amount for a battery about the size of a pack of cards (3.5 by 2.5 by 0.9-inches). This can be output about 17 Watts (15 Volts/1.4 Amps), about the same as others in this roundup. The only control is a single button and four LEDs that show the charge level, but the large battery does mean that you should be able to charge an iPhone XS battery two and a bit times. That’s enough to stay in touch on a weekend camping trip.

曾经失去了你充电电缆吗?你不会的HyperJuice USB-C & Lightning battery thanks to its built-in Lightning and USB-C cables. When not in use, they tuck into the Hyperjuice, so their sensitive plug ends are protected. When the time comes to power something up, however, things can get a little awkward, as the cables are only four inches long. This can make it difficult to use attached electronics. Making a call on a smartphone tethered to a four-inch cable is not the best user experience. The HyperJuice, at 5.7 inches tall and just 0.6 inches thick, is relatively portable. You can easily slip it inside of a backpack or purse.

In addition to the pair of built-in cables, there's also a USB-C port. However, the port is designed for charging only, so you can’t use it to charge a third device. The built-in USB cable can also be used to charge the battery. When it's time for a quick powerup, just connect the HyperJuice to a charging laptop and the laptop will charge the battery.

Weighing in at about 9.5 oz and measuring 5.6 inches long, the Mophie Powerstation Plus is an impressive slab of a battery. It holds 6,000 mAh of power, which can be dispensed through its built-in USB-C charging cable or via its USB-A port.

The Powerstation Plus’ support for Power Delivery (PD) means it can do some clever stuff to make charging easier, like increasing the voltage sent over the USB-C connection to 10 Volts. This trick doesn’t mean it charges any faster, however. Instead, it makes the power transfer slightly more efficient.

The Powerstation Plus has a maximum output of 18 Watts. We were able to get full charges using the Samsung Note 8 and an iPhone XS at once, as the combined draw is about 18W. However, when we replaced the Note 8 with an iPad (which can suck down 18W on its own), the charging speed of the iPhone dropped considerably, as both devices have to share the 18W of juice on offer. Our only real complaint is this battery’s integrated cable, is only four inches long. In order to charge a smartphone while the cable is plugged into it, you’ll have to hold both the battery and the handset in the same hand. That’s pretty awkward.

It’s worth noting that there’sanother version of this batterythat offers a built-in cable with Lightning and micro USB connections.

Like the Fuse Chicken Universal, the Anker PowerCore Fusion combines power supply and a USB battery in one neat package. Plug it into a wall socket and it works as a wall charger with a USB-A power supply, providing 14 Watts to each of its two USB-A ports. Unplug the PowerCore Fusion from the wall socket, and your devices will continue charging from the Fusion’s built-in 5,000 mAh battery—enough capacity to charge an iPhone XS roughly one and a half times.

The PowerCore Fusion isn’t as compact as batteries that don’t include the power supply: the Metecsmart 5000 offers the same amount of portable power in a far smaller package. But, as the PowerCore Fusion is both a power supply and USB battery, it’s a great pick for travelers with frequent access to a wall socket for those who want to keep their phone charges on the go.
