7 Best Ultra High Capacity Power Banks

There may be a lot of factors that go into your decision when buying a power bank, but one of the main things is always going to be the capacity. In this article, we’re going to rank the best ultra high capacity power banks.

The rankings are primarily based on capacity, but we’ll look at some other considerations as well, so you have more information to make your decision besides just that.

1. Renogy 72000mAh Laptop Power Bank with 12V Socket

Renogy 72000mAh Laptop Power Bank with 12V Socket

  • Capacity: 72000 mAh / 266 Wh
  • Dimensions: 9” x 4.9” x 1.7”
  • Weight: 52.8 oz/1496 g
  • Ports: 1 USB Type-A, 2 USB Type C, 1 DC, 1 car lighter
  • Charging Time: 4 Hours
  • Passthrough Charging: Yes

Check Price on Amazon.com

The Renogy Laptop Power Bank is by a wide margin the highest capacity entry on this list. The combination of its high capacity and lighter style part even make it suitable for charging more powerful devices than just laptops.

That said, laptops are where this power bank shines. The DC output port supports 2V/5A, 16.5V/4A, 20V/3.5A, 24V/2A devices, and has a modular tip with support for 19 different charging ports. It also features pass-through charging, so if the power bank is plugged in, it will charge devices from that source first.

The additional USB-A port and USB Type C port can be used simultaneously with the DC port, providing extra support for those with multi-device needs. And it has a LED power indicator, making it easy to track power consumption.

It has protection from overheating, short circuits, power surges, and overcurrents. It’s not waterproof (though many aren’t) and it’s not quite as rugged as some others, so avoid major impacts where you can.

The only major downside to this device is when it comes to portability. Where most power banks are comparable in size to a phone, this one is closer to a large paperback book. The capacity is also well above the TSA limit for carry-on, so it can’t be taken on flights.

2. MAXOAK Laptop Power Bank 185Wh/50000mAh

MAXOAK Laptop Power Bank 185Wh/50000mAh

  • Capacity: 50000 mAh / 185 Wh
  • Dimensions: 1 x 5.3 x 1.3 in
  • Weight: 77 lbs
  • Ports: 4 USB Type A Ports, 2 DC Ports
  • Charging Time: 7 Hours
  • Passthrough Charging: Yes

Check Price on Amazon.com

As you might have picked up from the name, this MAXOAK power bank focuses first and foremost on laptops. With 2 DC ports (one 20V/3A, one 16.8V/2.5A) and a 14 piece connector set, it can charge most laptops, but not those with USB-C charging ports.

It’s no slouch for USB powered devices either. It’s got 4 USB Type A ports, which can all be used at once, as long as you’re not using the DC ports. Using the DC ports limits the number of USB ports available.

It includes a powerful charging cable with a brick adapter and supports pass-through charging. An LED indicator displays power level and usage.

The power bank also includes surge protection, short circuit protection, and overcurrent protection. It has an aluminum alloy shell, so it’s one of the sturdier options on this list, but still not technically shock resistant.

It includes a carrying case, which gives it a slight advantage in terms of portability, but it’s still very large, fairly heavy, and well over TSA limits.

3. Krisdonia 50000mAh Ultra High Capacity Power Bank

Krisdonia 50000mAh Ultra High Capacity Power Bank

  • Capacity: 50000 mAh / 185 Wh
  • Dimensions: 68” x 5.91” x 1.1”
  • Weight: 55 lbs
  • Ports: 1 DC Port, 1 USB Type C Port, 2 USB Type-A ports
  • Charging Time: 8 Hours
  • Passthrough Charging: Yes

Check Price on Amazon.com

The Krisdonia Laptop power bank is a highly versatile charger. With a USB-C port and a 28 piece DC adapter, and an adjustable output, it can charge just about any laptop.

There are also two USB-A ports, which allow you to charge two phones or tablets at the same time with quick charge capability.

This power bank includes a unique display, which shows the exact charge percentage, and the current DC output selected.

It also includes over and under-charge protection, meaning it will shut down if it detects that the selected output is too high for your device.

The Krisdonia power bank is the smallest of the 50000 mAh options on this list and comes with a carrying case, so it’s a slightly more portable option, but it’s still too many Watt-hours to carry on a plane.

4. Crave 50000 mAh PowerPack Portable Battery Pack Charger

Crave 50000 mAh PowerPack Portable Battery Pack Charger

  • Capacity: 50000 mAh / 185 Wh
  • Dimensions: 2” x 5.4” x 1.3”
  • Weight: 3 lbs
  • Ports: 2 USB Type C Ports, 2 USB Type A ports.
  • Charging Time: 6 Hours
  • Passthrough Charging: Yes

Check Price on Amazon.com

The Crave PowerPack is designed for users who need to maintain power for several mobile devices over an extended period of time. You can also purchase an adapter allowing the USB-C port to connect to 19 different DC charging ports.

All four ports have fast-charge capability and can be used simultaneously, although fast charge might be hampered if you are using all four at once.

A LED displays the current charge level.

The power bank can be charged through any of its ports, but the manufacturer recommends charging through the 60W USB-C port. It also has pass-through charging, though you’ll need to be charging it through the recommended 60W USB-C slot to get any significant benefit from this feature.

It has overcharge protection but is not surge resist, shock resistant, or waterproof.

With this one, we also see some issues with portability. It’s only slightly smaller than the Renogy and actually a bit heavier. It’s also significantly over the allowed TSA limit for Watt-hours.

5. ROMOSS 40000mAh Power Bank

ROMOSS 40000mAh Power Bank

  • Capacity: 40000 mAh / 148 Wh
  • Dimensions: 67” x 3.21” x 1.73”
  • Weight: 98 lbs
  • Ports: 2 USB Type-A Ports, 1 USB Type C Port
  • Charging Time: 16 Hours
  • Passthrough Charging: Yes

Check Price on Amazon.com

This ROMOSS power bank has an excellent capacity for charging mobile devices. It can charge up to three devices at once, with fast charging available through the USB-C port and one of the USB-A ports.

There’s a USB display that shows the current power level, as well as current and voltage used, allowing precise monitoring of usage.

There are numerous safe charging features, including protection from overheating, overcharging, overcurrent, surges, and short circuits.

The pack is fairly small, but it’s a bulkier shape, so it might not slip easily into a case or pocket. It is low enough capacity to go through TSA with special permits.

It’s got a couple of points against it though. The power bank doesn’t have a DC outlet, so it can’t charge laptops and larger devices, and it takes longer to recharge than even some of the higher capacity options on this list.

6. RAVPower Portable Charger 30000mAh Power Bank

RAVPower 30000mAh

  • Capacity: 30000mAh / 111 Wh

  • Weight: 1.3 lbs
  • Ports: 1 USB Type-A, 1 USB Type-C
  • Charging Time: 2.5 Hours
  • Passthrough Charging: Yes

Buy on RavPower.com

The RAVPower Portable Charger is another option specifically for those looking for a more compact option. This is the big brother of the highly popular PD Pioneer 20000mAh power bank by RAVPower. They’re both part of the PD Pioneer series that also includes a 10000mAh and a 15000mAh version.

This is a sleek power bank, make out of industrial-grade plastic and which features one USB Type-A and USB Type-C output. It protects against overcharge, surges, and short circuits. It does not protect against overheating but is designed for more optimal heat dissipation than some other options. It also features an 8 point LED strip on its side, which shows the approximate current charge level.

As far as portability goes, this is a power bank that you can easily carry in your backpack as you go around your day. It’s still technically too high to go through TSA without special permission, but can be carried on if you obtain that permit.

7. Anker PowerCore+ 26800mAh PD Power Bank

Anker PowerCore+ 26800mAh PD Power Bank

  • Capacity: 26800 mAh / 100 Wh
  • Dimensions: 68 x 3.54 x 2.36
  • Weight: 6 lbs
  • Ports: 2 USB Type A Ports, 1 USB Type C Port.
  • Charging Time: 4 Hours
  • Passthrough Charging: Yes

Check Price on Amazon.com

The Anker PowerCore plus is another TSA friendly power bank. There’s a USB-C cable as well, so it can also charge certain laptops. It does charge through the USB-C port, so passthrough charging is only available on the two USB-A ports.

The LED display is a 10 point ring, which gives you a more accurate display of remaining power than other non-numeric displays.

It has overcharging protection, but not much else in the way of safety features.

It’s a longer and slimmer bank, which makes it more portable, but like most high-capacity chargers is still not going to fit easily into your pocket.


If you’re shopping for an ultra-high capacity power bank, be sure to consider not just capacity, but also the functions and charging time. All the options on this list are excellent in terms of capacity, so pick the one that has the features that you’re most likely to need.
