What to Look For in a Portable Charger in 2022

The best portable chargers charge all of your essential devices. They come in all shapes and sizes, from small, 2,000 mAh (milliamp hours) charging sticks to high-capacity power banks packing more than 30,000 mAh of pure electricity.

Choosing the correct portable charger comes down to three key criteria: capacity, size, and charging time.

Portable chargers run capacity anywhere from 2,000 mAh to 30,000 mAh. Small 5,000 mAh chargers are typically suitable for two full smartphone charges, whereas a 20,000 mAh portable charger can charge devices with larger batteries, like laptops, several times over.

In addition, portable chargers come in different sizes and weights. Pocket-sized portable chargers are easy to carry but generally have a single USB port. Larger capacity portable batteries weigh more but charge faster and hold additional USB ports to charge two or more devices simultaneously.

Lastly, charging time is important. Fast chargers can charge a smartphone from zero to full within 40 minutes, whereas pocket-sized and solar power chargers may take more time. You need to weigh charging time against the charger size in order to find the right product for you.

Consider the devices you plan on charging, your device’s capacity, the number of devices to charge, and how frequently you have to access a wall charger. A portable charger that doesn’t fit your needs will likely just sit at home unused, so definitely think about what you need.

Now, keep reading to learn more about our picks for the best portable chargers.

Best Portable Charger Overall: Anker PowerCore Slim 10000

Pros

  • Sleek, minimalist design
  • PowerIQ and VoltageBoost optimizes charging speeds
  • Fireproof casing, overcharge, and short circuit protection

Cons

  • Limited capacity (18w output)

The Anker PowerCore Slim 10000 Portable Charger takes our top award for the best overall portable charger. Its efficiency is on point, with 10,000 mAh good to charge an iPhone 12 two times.

Recharging time from zero to full is modest, taking roughly 6 hours. It also rocks with an ultra-slim profile and fits comfortably in a front or back pocket. With a light, textured surface that mimics plaid, this portable charger also just plain looks good.

The PowerCore Slim also boasts a proprietary technology called PowerIQ, which identifies all connected devices and automatically adjusts voltage output to maximize charging speed.

A separate proprietary feature, VoltageBoost, also helps smoothen erratic voltage output due to cable resistance. Expect it to recognize your device and offer uninterrupted charging speeds this way.

Although not the most rugged option out there, the Anker PowerCore Slim 10000 carries all essential safety systems (e.,g. overcharge and short circuit protection), in addition to fireproof casing and temperature controls.

Our only downside with the Anker PowerCore Slim 10000 is that it can only charge a single device at a time. However, its exceptional build quality, fast/consistent charging, and valuer price point are well worth it.

Pros

  • Only 0.5 inches thick
  • Can power an iPhone 13 up to 3 times
  • Displays

Cons

  • Does not include plug for recharging
  • No integrated cables

The Iniu Portable Charger is an excellent, cheap option for users with only one device to charge regularly. Using triple 3A outputs, it can charge up to three devices at the same time. From zero to full charge, its 10,000 mAh capacity is enough to power an iPad Air once and an iPhone 13 up to 3 times.

Plus, unlike the Anker PowerCore Slim 10000, the Iniu Portable Charger comes with a power indicator. Curiously shaped like a pawprint, it lets you know how much remaining juice there is.

We also love the fact the Iniu Portable Charger is super slim. At only 0.5 inches thick, it is pocket and purse-friendly. For the price point, this portable charger offers a nice combination of capacity, size, and triple 3A outputs for multi-device charging.

Pros

  • Includes wireless Qi charger
  • Enables pass-through charging
  • Comfortable, soft-touch rubber construction

Cons

  • Unintuitive menu system

The Omni 20 Portable Charger is our preferred choice for laptops. It is an absolute monster of a portable charger, with a 20,000 mAh battery capacity, a USB-C port, a wireless Qi charger, and two USB-A ports.

It also comes with pass-through charging, converting it into a universal power adapter that charges itself while charging other devices.

One of our favorite features of the Omni 20 Portable Charger is its design and construction. A sharp LCD shows remaining power, and a soft touch rubber construction helps absorb shock and provides grip in tight quarters.

The Omni 20 isn’t the cheapest portable charger around, but it’s worth the price of admission.

Goal Zero

Pros

  • Rugged construction
  • Depicts solar power strength using LED indicators
  • Includes holes for hanging

Cons

  • Cannot fold entirely flat
  • Slower charging time than traditional portable chargers

The Goal Zero Nomad 7 Portable Charger is a smart option for the outdoors, where you are often without access to power outlets.

Unlike traditional brick-style portable chargers, this portable solar charger offers a folding 7-watt solar panel with a detachable kickstand for positioning to make sure you catch the sun’s rays. It also comes with a vented pocket to prevent overheating.Β There’s also a LED indicator, which uses a series of 4 LED lights to indicate how strong solar power is at the moment.

Note, however, this unit only provides power when exposed to sunlight and does not hold an actual charge. That’s an unfortunate downside, but you can pick up a different portable charger to make sure you have a battery pack when needed.
