It’s hard to find another portable charger to beat the Omnicharge Omni 20+ since it does everything well. It offers a massive 20,000mAh charge capacity as well as fast charging.

The Omni20+ can fast-charge at up to 18W for cell phones over USB-A and up to 60W charging over USB-C for laptops. It also offers 10W wireless Qi charging for devices supporting it.

All devices connected to the Omni20+ use Quick Charge 3.0 for a fast recharge. Its 100W AC/HCDC outlet allows you to charge laptops, cameras, and drones that don’t support USB charging features.

This beast of a portable charger doesn’t come cheap though. At $200, it can meet all your portable power needs.

2. INIU 10000mAh Portable Charger

INUI is a lesser-known brand yet it’s noteworthy to compare with Anker’s charger, the next brand on this list. One can argue that the former is better than the latter.

INIU’s 10,000 mAh has a portable design and quick short-term charging. It’s one of the best portable chargers because its speed and charging time are some of the highest on the charts.

The INUI portable charger also has two USB-A output ports. This extra port is crucial when you need to charge two devices or help a friend recharge their gadgets.

INUI’s charger holds its own during benchmark tests against the more famous Anker. The INUI charger stands out by a small margin in a 15-minute and 1-hour timed charging test. It managed a 22% and 78% charge respectively.

These numbers are within 1 to 2 percentage points more than Anker’s charging times. However, INUI isn’t the fastest when getting to a full charge.

The INUI portable charger also offers a longer warranty with its three-year plan. It may be an unfamiliar brand, but it’s one of the best phone chargers around.

3. Anker PowerCore Slim 10000

Anker’s PowerCore Slim 10000 might only have one output port. However, it still packs a lot of juice and offers fast charging times. It offers a great balance between power and affordability.

As we said, Anker’s charger performs almost the same as INUI’s charger. The former offers a cheaper price.

You should get a full charge for your phone around two or three times. It depends on whether you have an Android or an iPhone. As for charging time, the PowerCore Slim 10000 was able to fully charge an iPhone 12 in an hour and 56 minutes.

It also comes with fast charging technology. However, it doesn’t support Qualcomm’s Quick Charge. Still, expect fast charging times from this portable charger.

4. Poweradd Slim 2

The Poweradd Slim 2 is perfect for people who only need a little more juice to top up their devices. Some people don’t like carrying bulky bricks as their battery chargers. The compact Poweradd Slim 2 is one of the best portable phone chargers when saving space.

It comes in a small cylindrical form factor that can fit in your pocket. The Poweradd Slim 2 is less than 4 inches long, an inch thick, and weighs 4.4 ounces.

Packed in this small frame is a 5,000mAh capacity. It has more than enough juice to give most smartphones a full charge.

Poweradd’s charger also comes with overcharge, overvoltage, and overcurrent protection. However, it doesn’t support the latest fast charging technology. Regardless, its charging speeds are reasonable enough.

It has a single USB-A output and includes a micro-USB charging cable. The single output port means you can only charge one device at a time.

The Poweradd Slim 2 is also affordable at $11. It comes in different colors so choose one that suits your tastes.

If you’re looking for a charger that can take you off the grid, this charger is for you. The Renogy E-Power allows you to charge your devices using solar power. Using this charger can contribute a lot to reducing your carbon footprint.
