Anker PowerCore II 20,000

best portable chargers Anker PowerCore II
  • Capacity: 20,000mAh
  • Outputs: 2 ports (18W and 12W)
  • Weight: 369g (13oz)
  • Price: $50
  • Time to fully charge: Around 5 hours

We’re big fans of Anker’s understated and practical designs. The PowerCore II packs in a huge 20,000mAh capacity without being ridiculously big, though it is something you’ll want to sling in a bag rather than your pocket. It features two USB outputs. PowerIQ 2.0 can put out up to 18W, which breaks down to 3A at 5V, 2A at 9V, and 1.5A at 12V. PowerIQ 1.0 can put out 12W up to 2.4A at 5V. Regardless of your device, you should be able to get decent charging speeds from this portable battery. The only thing it lacks is a USB-C port.

Compared to previous Anker offerings, there are a couple of new features here. The power button is now round and it houses a ring of white LEDs, which are designed show you how much power remains. There’s also a textured surface on the outside, so it’s less likely to slip out of your hand or slide away from the back of your phone while you’re charging your device.

This battery’s robust capacity should also provide you with more than enough power to fully charge a Galaxy S8 four times, and it will charge an iPhone 8 more than six times. It’s also quick to charge, at just five hours, provided you have a decent wall charger (not included). All in all, this portable battery charger represents great value for the money.

Tronsmart Presto Power Bank

Tronsmart Presto Power Bank
  • Capacity: 10,000mAh
  • Outputs: 2 ports (3A/18W and 2.4A/15W)
  • Weight: 210g (7.4oz)
  • Price: $23
  • Time to fully charge: Around 4 hours

This compact portable charger is slim and light, but packs a big capacity of 10,000mAh. It has two USB ports for charging up your devices. The green one can put out 18W and supports Qualcomm’s Quick Charge 3.0 standard, as well as Huawei’s FCP, so it can juice up certain phones very quickly. You can expect two or three charges from this battery for most smartphones.

The design is an unobtrusive black and the outer shell is finished in soft-touch plastic, so it’s comfortable to handle. There’s a button on the side to turn it on, and you’ll find a typical four LED battery level indicator on the top. It can be charged up via the MicroUSB port and should juice up quickly, provided you use a decent cable and wall charger with it.

It comes with a USB-A to MicroUSB cable in the box and a travel pouch. Tronsmart also offers an 18-month warranty.

Belkin Pocket Power Charger

Belkin Pocket Power
  • Capacity: 5,000mAh
  • Outputs: 1 port (2.4A)
  • Weight: 131g (4.6oz)
  • Price: $25-plus
  • Time to fully charge: Around 5 hours

Here’s a fairly small, lightweight option from Belkin that will charge up an iPhone around one-and-a-half times, and should provide at least one full charge for most other smartphones. There’s a single USB port that puts out up to 2.4A, and a MicroUSB port for charging it up that’s rated at 2A.

It’s durable, with a plastic casing that comes in your choice of pink, black, or silver. It’s small enough to slip into a pocket or handbag. There’s a power button on the side with four LEDs that light up green to show remaining power in 25 percent chunks. You get a 6-inch MicroUSB to USB cable in the box with it.

If you need more capacity, then Belkin does offer 10,000mAh ($40) and 15,000mAh ($50) models that sport two USB ports for charging. Belkin offers a special $2,500 Connected Equipment Warranty that guarantees a repair or replacement if your device is damaged by an electrical charge while properly connected to the charger.

iQunix MiniPower Portable Charger

iQunix MiniPower Portable Charger
Simon Hill/Digital Trends
  • Capacity: 3,350mAh
  • Outputs: 1 port (1.5A)
  • Weight: 79g (2.8oz)
  • Price: $13
  • Time to fully charge: 3 to 4 hours

Possibly the most portable pick of the bunch, the MiniPower from iQuinix is ideal for slipping into your handbag and forgetting about until you need it. Finished in brushed aluminum that comes in your choice of black, gray, red, pink, or white, this diminutive charger packs a decent 3,350mAh capacity. There’s only one port, which can put out up to 1.5A, so there’s no fast charging here.

It comes with a felt pouch and a short, nylon-braided, USB-to-Micro USB cable. It is quite slow to charge phones and to charge up itself with that 1.5A limit, but it is also reasonably priced, durable, and very small. When you plug it in to charge a single LED will show red if it needs to be charged further or go green when fully charged, but that’s your only indication of remaining power. It will fully charge an iPhone, but for a lot of phones with bigger batteries, you’re just looking at a top-off.

BlitzWolf Qualcomm Quick Charge 3.0 Power Bank

BlitzWolf QC 3.0 Power Bank
  • Capacity: 5,200mAh
  • Outputs: 1 port (18W QC 3.0)
  • Weight: 156.3g (5.51oz)
  • Price: $15
  • Time to fully charge: 3 to 4 hours

This power bank offers quality and a range of features at an attractive price point. It’s a chunky device that measures just under an inch thick, 4 inches long, and just under 2 inches across, so it will fit neatly in your pocket or bag.

It’s extremely simple to use, too. There’s a power button that brings the four LEDs to life, giving you a rough indication of the remaining power. There’s a single USB output and a Micro USB input for charging. The output supports Qualcomm Quick Charge 3.0 technology, which is fast and rare in a charger of this size.

The output is also smart enough to determine what you’ve plugged in, so it can cover everything in a 3.6V to 12V range. You also get a Micro USB charging cable in the box. You can expect around three charges for something like the iPhone 8 or a charge and a half for the Galaxy S8. There are also 9,000mAh ($30) and 15,600mAh ($40) versions of this charger.

Nifty External Battery

Nifty Portable Charger
  • Capacity: 6,800mAh
  • Outputs: 2 ports (USB-C 3A and USB-A QC3.0 3A)
  • Weight: 157g (5.5oz)
  • Price: $60
  • Time to fully charge: 2 to 3 hours

We’re impressed by a couple of the features on this portable charger, so it definitely earns its name. The battery capacity isn’t huge, but it’s a compact device finished with a textured plastic that comes in red, gray, or black, with a glossy Nifty logo. It offers a USB-C and a USB-A port, which supports Qualcomm’s Quick Charge 3.0. Each port is also capable of outputting 3A, but total output is capped at 4.8A. It can charge two devices simultaneously.

What we really like about the Nifty is the lack of buttons. You simply tap it and both the five-LED array and the USB port light up to show you how much power remains, which is ideal if you’re fumbling in the dark. Charging speeds are fast, too, regardless of your device. It comes packaged with a 3-foot, flat USB-A to USB-C cable and a shorter, flat USB to Micro USB cable. Both are orange, tangle-resistant, and sport Velcro ties. If you want to charge your iPhone, however, you’ll need to provide your own USB to Lightning cable, or buy a spare.

As nifty as the Nifty is, it’s expensive. You can get a higher-capacity portable charger for far less, even with a USB-C port. It likely won’t be as stylish or sport the illuminated port, but if you’re on a budget, you can probably live without the extras. If price is no object, however, then we can recommend the Nifty.

Moshi IonSlim 5k

Moshi IonSlim 5K Battery Charger
  • Capacity: 5,150mAh
  • Output: 2 ports (Type-C and USB-A 3A total)
  • Weight: 143g (5.04oz)
  • Price: $55
  • Time to fully charge: 4 hours

You’ll like the look and feel of this svelte charger. It’s just 8.5-millimeters thick and has a durable and stylish aluminum finish. There are two ports, one USB-C and one USB-A, which offer a total output of 15 watts (3A). The USB-C port is also used to charge the IonSlim. It ships with a 6-inch, reversible USB-C to USB-A cable, which can be used to charge the battery pack or another device.

Next to the two ports, you’ll find the power button and a four-LED array that displays the remaining power. You can’t charge two devices at once, but you can charge the battery pack via USB-C and use USB-A to charge your phone at the same time. You can charge most phones at least once with this battery pack, and it will probably provide a couple of charges for the iPhone 7.

Flux Portable Charger

Flux Portable Battery Charger
Simon Hill / Digital Trends
  • Capacity: 4,000mAh
  • Output: 2 built-in cables (1A and 2.1A)
  • Weight: 92g (3.2oz)
  • Price: $26
  • Time to fully charge: 3 to 4 hours

This is one of the slimmest portable chargers we’ve ever come across. If you’re really looking for something pocket-sized, the Flux Charger is worth more than just a glance. It’s a mere 7.8-millimeters thick and measures 108 x 62.8 millimeters. It’s also incredibly light, but holds enough power to fully recharge your phone at least once, possibly twice. It’s finished with a durable black or white aluminum, and features two built-in cables, a Micro USB cable, and a MFi-certified Lightning cable. There’s also a Micro-USB port for charging, which comes with a short Micro USB to USB cable.

Tap the small button on the side, and the four tiny LEDs light up to show remaining power. It doesn’t support fast charging, though, and we found that it took a couple of hours to charge the large battery in the Samsung Galaxy S7 Edge. Fortunately, it should fully charge an iPhone in around an hour. The input for charging it is 1.5A, so it takes a while to fully charge, but it does support pass-through charging, so you can plug it into the wall and your phone at the same time. If you like the design, but you need more power then check out the 10,000mAh Flux Charger Plus for $52.
