Portable chargers keep your devices charged while you are on the go. They can charge a wide range of devices, including phones, tablets, Nintendo Switch consoles, and even laptops when we need them the most. You will need a dependable portable charger because you will inevitably find yourself out of the house with low battery life.

We ran a battery (pun intended) of tests on ten of the best portable chargers on the market, including models from both major brands and well-known competitors. Testing included determining how quickly devices charged and how many full phone chargers each power bank could store. While these specific portable chargers appear on bestseller lists on a regular basis, they differ in a number of important ways.

Our tests were carried out on the same iPhone 12, with the brightness set to 100%. We evaluated each charger in four ways: how much charge is added in 15 minutes, how much it was added in an hour, how long it took to recharge an iPhone from dead to 100 percent, and how many times it could recharge the same iPhone 12 from dead.

INIU 10000mAh Portable Charger


  • Capacity: 10,000mAh
  • Output Ports: 1x USB-A
  • Input Ports: 1x microUSB
  • Weight: 6.4 ounces
  • Measurements: 3.6 x 2.3 x 0.9 inches
So, if you are always trying to keep your phone at 100% charge or are concerned about running out of battery in the wilderness, we have got the information you need. This includes which chargers have which types of ports and how many, allowing you to charge multiple devices at the same time. Even if your phone is listed on our list of the longest-lasting smartphones, you could benefit from this portable insurance package on your next adventure.
Anker (the usual standard-bearer) lost to INIU’s 10000 mAh charger in a shocking upset for the top spot. This brick is one of the best portable chargers on the market. Not only are its charging times and speeds near the top of the chart, but it also has two USB-A output ports as opposed to the Anker PowerCore Slim 10000’s single USB-A charging port. And because that second port can mean the difference between powering a secondary device while charging your phone (or helping a friend in need), we are giving the INIU the edge.
This INIU charger performed admirably in 15-minute and 1-hour timed charging (at 22 percent and 78 percent), with times that were 1-2 percentage points faster than the PowerCore Slim’s. It only failed to beat the Anker to fill a full phone once, with a 2-hour time that was four minutes slower than the Anker. Both chargers refilled about 2.2-2.25 iPhone 12s, so it is a virtual tie. INIU also offers a longer warranty: its 3-year plan lasts twice as long as Anker’s 18-month guarantee.

Anker PowerCore Slim 10000

2. Anker PowerCore Slim 10000


  • Capacity: 20100mAh
  • Output Ports: 2x USB-A
  • Input Ports: 1x microUSB
  • Weight: 12.6 ounces
  • Measurements: 6.6 x 2.4 x 0.9 inches
The Anker PowerCore Slim 10000, which is a little heavier than the INIU 10000 pack, is our number two pick (and still one of the best portable chargers) (7.3 ounces to 6.9 ounces). However, if it had a second USB-A output port, it would have taken the top slot. This was due to its charging times being so close to the INIU brick (21 percent in 15 minutes, 76 percent in an hour), and its overall time to fill an iPhone 12 being 4 minutes shorter, at 1 hour and 56 minutes.

However, because it is so close to the INIU, we must keep it as the #2-ranked portable charger. These bricks are so close that they are practically within testing margins of error. If you only need to charge one device at a time and the Slim 10000 is significantly less expensive than the INIU, go for it.

Poweradd Slim 2

3. Poweradd Slim 2


  • Capacity: 5000mAh
  • Output Ports: 1x USB-A
  • Input Ports: 1x micro USB
  • Weight: 4.4 ounces
  • Measurements: 3.9 x 1.3 x 1.2 inches
Not everyone requires a full brick to charge their phone. Sometimes all you need is the peace of mind that comes with a small cylinder of juice. And, once again, the Poweradd Slim 2 and the competitive Anker 5000 mAh stick have comparable numbers. The Poweradd won the 1-hour charging window (67 percent to 62 percent) but lost the 15-minute window (62 percent to 67 percent) (16 percent to 19 percent ).

In terms of internal capacity, the Poweradd did not actually beat the Anker, but it came close, with a 97 percent to 105 percent margin of victory. And the difference is not significant enough to warrant a ding. So, what makes the Poweradd stick so high on our list of the best portable chargers?

It is frequently the cheapest on this list, typically costing around $10.99 (nearly half the price of comparable chargers). It also weighs slightly less than the 4.7-ounce Anker PowerCore 5000. The updated Poweradd Slim 2(opens in a new tab) has received over 500 reviews and a 4.4 out of 5 rating on Amazon. “It is significantly larger, but with four times the charge capacity of the usual little cylinders.” It can charge both a kindle and a smartphone.

INIU 20W 20000 mAh power bank

4. INIU 20W 20000 mAh power bank


  • Capacity: 20,000mAh
  • Output Ports: 2x USB-A, 1x USB-C
  • Input Ports: 1x USB-C
  • Weight: 12.6 ounces
  • Measurements: 6.4 x 3.8 x 1.8 inches
USB-C is no longer a port of the future; it is a port of the present. While INIU’s 20-watt brick is a little heavy (it is the second heaviest on this list), its dual-function USB-C port makes it a clear favorite for one of the best portable chargers for those charging via the reversible port. You can charge it and other devices using the same USB-C cables, and there are two additional USB-A ports for charging other devices.

Furthermore, it delivered the best performance in the 1-hour charging window, charging our dead iPhone 12 to 81 percent of its capacity. And its 1-hour and 57-minute charge time for the iPhone is the second-best of the bunch, trailing only the PowerCore Slim 10000 by a minute. With 4.78 iPhone 12 refills, its high capacity of 20000 mAh meant it refueled an iPhone more than most of these chargers. This product has received 4.6 out of 5 stars from nearly 4,500 Amazon customers.

Poweradd EnergyCell 10000

5. Poweradd EnergyCell 10000


  • Capacity: 10,000mAh
  • Output Ports: 1x USB-A
  • Input Ports: 1x microUSB
  • Weight: 6.1 ounces
  • Measurements: 4.1 x 1.9 x 1 inches
The Poweradd EnergyCell 10000 does not appear to be a 10,000 mAh battery; it is small enough to be confused with a 5,000 mAh charger. However, it contains approximately two full iPhone 12 charges, making it a surprisingly long-lasting power supply and one of the best portable chargers overall.
Its 15-minute and 1-hour charging scores (20% and 71%, respectively) are on the higher end of the scoring ranges. The only slight disappointment is that it only has one USB-A out port, but given its small size, this is understandable.

However, portability is one of its main advantages, as you will not have your entire crew expecting you to keep their phones charged if you do not have a tank of portable chargers with you. This product has received 4.4 out of 5 stars from nearly 200 Amazon customers.
