5 Best High-Capacity Power Banks for Travel

Power banks or portable battery packs can be life savers when traveling. Whether you use them to charge your phone or laptop, a power bank is a must-have accessory if you’re going to be away from a wall outlet for a long time. And if that long time means a few hours in double digits, it’s even better if you have a high-capacity power bank.

A standard power bank may only be able to charge your smartphone or other low-powered devices a couple of times. However, a high-capacity power bank may even charge bigger devices like laptops multiple times. Along with a high capacity, it’s also important to have a high wattage for power output to charge large devices. We’ve made a list of some of the best power banks that fulfill both these needs to help you while traveling.

1. Anker 337 Power Bank

Capacity: 26800mAh | Ports: 3 x USB-A and 2 x micro-USB | Output Power: 15W

Anker is one of the most popular brands in this industry so if you get this power bank for yourself, you can be assured that you’re getting a reliable product. The overall footprint of this power bank is handy for the capacity that you’re getting. However, the output power is average so you can’t charge devices like laptops.

The Anker 337 is a 26800mAh power bank which means it is safe to carry on airplanes. Considering the efficiency parameters, you can expect to charge a phone with a 5000mAh battery about 4 times. There are 3 USB-A ports onboard that you can use to simultaneously charge 3 different devices at once.

As for the input, you get 2 micro-USB ports onboard which is unique. You can use both ports simultaneously to charge the power bank at a combined charging speed of 20W. Anker claims that you can charge the power bank fully in about 6 hours using both ports together and a fast-charging adapter.

The biggest drawback of this power bank is the lack of fast charging for both the input and output. You can charge phones at a maximum of 15W which seems a bit archaic. It’s still decent for the price and the capacity you’re getting, though.

2. Baseus 100W Blade Portable Charger

Capacity: 20000mAh | Ports: 2 x USB-C and 2 x USB-A | Output Power: 100W

While the Anker power bank is specifically meant for smartphones and accessories, the Baseus 100W power bank can be used for many more products. You can even charge your laptop using this power bank, thanks to the USB-PD output port. Furthermore, you can even charge the power bank via USB-PD at 65W which is excellent.

This high-capacity power bank from Baseus is useful if you want to charge laptops while you’re on the go. The 20000mAh capacity is slightly lower than the other power banks on this list but by no means is it small. Unlike most power banks of this capacity, this one is slim but slightly larger and almost resembles a passport.

There are 2 USB-C ports onboard with one of them used for both input and output. You also get 2 USB-A ports to charge phones or smaller accessories. Baseus has also provided a small display to check the remaining battery level. Apart from the 100W output, the power bank itself can charge at 65W which means you get a full charge in almost 1.5 hours.

3. FlashFish 120W Portable Power Station

Capacity: 26400mAh | Ports: 2 x USB-C, 2 x USB-A, DC 12V, AC Socket | Output Power: 100W

If 2-3 ports aren’t sufficient for your usage, here’s a much large power bank that will probably fulfill all your power needs while traveling, albeit in a large form factor. The FlashFish power station is huge so while it may not be wise to carry it on an airplane, it’s a great companion on road trips or if you plan on going camping.

The biggest advantage of the FlashFish portable power station is the sheer selection of output ports. Apart from the usual USB-C and USB-A ports, you also get DC in and out ports to charge the power bank itself or other devices at 12V. That’s not it! You can connect a full-fledged power plug to the AC socket and mimic a wall outlet.

This is one of the best features of this power bank. The rear of the power station also has an LED light that you can use during emergencies or for reading. The brand also sells solar panels that you can purchase to charge the power station outdoors. The 100W output is the icing on the cake to charge large devices.

4. SinKeu Portable Charger with AC Outlet

Capacity: 24000mAh | Ports: 2 x USB-A, DC 15V, AC Socket | Output Power: 65W

Buy

Here’s yet another power bank that has an AC outlet to plug in your large appliances or devices. The SinKeu portable charger can charge your laptop or other high-power devices at 110V/65W while your smartphones or other accessories can charge via the USB-A port. There’s a small OLED panel to display the battery percentage.

If you want a power bank that has an AC socket without getting a bulky power station like the FlashFish one, this is your solution. However, the biggest drawback is that you’re missing out on USB-C ports with this power bank which is an absolute necessity for most high-power devices.

It also means that you cannot fast-charge your smartphones via USB-PD. You do get a DC-IN port, though, to quickly charge the power bank at 30W. Considering the high capacity, it’s still not going to be as fast as some other power banks that charge at 65W. If you want a compact power bank with an AC socket, this will serve you well.

5. Shargeek Storm 2 100W Transparent Power Bank

Capacity: 25600mAh | Ports: 2 x USB-C, 1 x USB-A, 1 x DC | Output Power: 100W

The Shargeek Storm 2 is easily one of the most unique power banks out there. Not only is it awesome in terms of looks but it also has a cool screen that displays the input and output wattage along with other charging info. It has all the ports you need to charge everything from a laptop to a smartphone at high speeds.

This power bank is nothing like you’ve seen before. It has a completely transparent housing through which you can see all the internal components to geek out on. If you’re a tech aficionado, you’re surely going to appreciate the design. It’s almost got a Cyberpunk-like look with yellow accents running all over.

The maximum output via the USB-C port is 100W which is more than sufficient to charge most high-power devices. The IPS display is helpful for all the nerdy details you need to see while your devices or the power bank itself is charging. Another big advantage of this charger is that you can juice it up to 100% in just 90 minutes with a 100W charger.

It’s a power-packed accessory with all the tech coolness that you want, but it comes at a price. The Shargeek Storm 2 is quite expensive but for someone who appreciates the design and the functionality of this large-capacity power bank, it might be worth the asking price.
