This is my favorite portable charger of all time. It’s been with me in a number of off-grid situations in various countries, and it has never let me down. It has enough capacity to keep my devices topped up between proper recharges, and enough power to charge everything from my earbuds to laptop.
And it’s still small enough to fit into cargo pants pocket, although you’d better have a belt!
If you want a big power bank and the ability to charge four devices simultaneously, the Zendure SuperTank Pro is among the best portable chargers.

Everything about the Omnicharge Omni 20+ is designed around power and ruggedness.
The exterior ABS/rubberized shell is capable of taking a pounding, the ports are well-designed, and the screen offers everything from at-a-glance information, to a deep dive into what’s going on.
Think of this power bank as a recharging computer.
The Omni 20+ is great choice for when I want an AC outlet away from civilization but don’t want to take a big power station.

Is it a portable power bank or a wall charger? It’s both!
You can keep the Anker PowerCore Fusion 10000 plugged in and use it as a charger. Or, take it on the go when you want to use it as a power bank.
I have one of these next to my bed. It charges my smartphone at night, and is always ready in case of a power cut, and when I need a power bank in a hurry.

Features: Capacity: 25000mAh / 92.5Wh | Magnetic Wireless Charger Output: 15W Fast Charge (10W for Android and non iPhone 12 devices) | Apple Watch Wireless Output: 5W | Maximum Power Output: 190W | Batteries: 5 x 21700 Panasonic Lithium Polymer Graphene Composite Battery Cells | Time to full charge from empty: 1 hr 10 min (with 100W input) | Dimensions: 6.24 x 3.4 x 1.12 inches | Weight: 1.28 pounds
The Flash Pro Plus is a chunky pack of aircraft-grade anodized aluminum and batteries. It weighs a reassuring 1.2 pounds, so it’s big. But it’s been with me in a lot of places where it isn’t easy access to a power outlet.
In the age of thin, lightweight devices, this thing is a monster! It’s also incredibly rugged, having survived a number of falls.
It houses five 21700 Panasonic lithium polymer graphene composite cells holding 25,000mAh of power. The power bank can push that power out of four ports and two wireless charger pads.
Yes, that’s right, ports and wireless.
This isn’t the largest capacity power bank here by far — in fact, given its size, the capacity is actually very low — but the recharge capability makes it a great choice for those in a hurry.

Which is the right portable power bank for you?
One size doesn’t fit all. And with so many options out there, it can be confusing to determine which power bank is the right fit for you. Most likely, the devices you need charged on the go will play a primary role in your choice. Power capacity and price will likely be factors in your decision.

How did we choose these portable power banks?
These are all products that I’ve tested and have been using for several months. I always have a power bank or two with me when I’m traveling, and this means that they get prolonged testing.
Here are some of the criteria that I look for:
- The power capacity is as stated by the manufacturer.
- The power bank outputs the power stated in the specification sheet.
- The product is durable and withstands prolonged use.
What size power bank do I need?
Tough question. If you want an emergency power bank to act as a backup, then a small 5000mAh power bank will do the job. If you want a lot of power, and perhaps the ability to charge up a laptop, then the bigger the better (and as big as you want to carry!).
Or, you might be looking for the Goldilocks of portable power banks. With these, you gain enough power to charge tablets or phones on the go.
What’s the largest power bank I can take on an aircraft?
Power banks up to 100Wh (100,000mAh) can be carried without approval. For power banks that fall between 100Wh and 160Wh, you will need permission from the airline.
Typically, you can contact the airline’s customer service ahead of your flight. Doing so this helps you understand their process for approval and can save you a lot of time at the airport, as customer service lines can be longer than a digital queue for Taylor Swift tickets.
Also, when going through normal screening at TSA, treat your power bank as you would a laptop, gaming console, or phone.
Are power banks waterproof?
There are some power banks that claim to be water-resistant. However, I’ve never been comfortable with the idea of getting a pack filled with lithium batteries wet. I always keep them dry. You should also keep them in a waterproof bag. That way, you prevent them from incurring water damage during rainy weather.
What do you think of power banks that have a built-in solar panel?
I have yet to come across a good one. I’m also not comfortable baking rechargeable batteries in the sun for extended periods. We’ve analyzed the best portable solar chargers that you can consider as an alternative.
However, keep in mind these are more suited for outdoor use. As solar technology continues to evolve, it’s possible that solar panels will be built into power banks moving forward.
Are there alternative power banks worth considering?
Yes there are. Check out the alternatives below:
