100Wh is one of the most common configurations you’ll see for a power bank. There are a few reasons, some having to do with it being a good capacity for charging multiple phones (or one phone multiple times), or even providing a full charge for a tablet or laptop. 100Wh is a good capacity, and with very few exceptions you’ll get more than enough use out of a power bank of that size.
All that aside, the main reason that so many power banks are 100Wh is that it’s the largest capacity that’s allowed on an airplane without special permits or certification. So if you frequently travel by air (honestly one of the most compelling reasons to consider a power bank) then a 100Wh power bank is the largest you can be guaranteed to not have any issues with.
Here are our top 5 picks for the best 100Wh power banks currently available.
1. Charmast 26800mAh/100Wh Power Bank with PD & QC 3.0
The main appeal of the Charmast PD power bank is that it’s scarcely larger than the phone you’ll be charging with it. It has numerous charging ports, including a USB-C port, lightning port, and smart quick charge enabled port.
It has passthrough charging, but charging speed and output will be severely limited while doing so.
It has a 4-point LED display, allowing you to monitor the current battery level to within 25%.
It also includes multi-layer safety protections, including overheating, overcurrent, and overcharge. It’s not shock or impact-resistant, though none of the options on this list are.
2. RAVPower 26800mAh/100Wh Portable Charger
The RavPower 26800mAh portable charger is a bit more compact, less than an inch thick in total, and exactly a pound. It’s a little thicker than a phone, but will still fit comfortably in a pocket or a compartment designed for mobile devices.
Both of its USB-A ports are 2.4V iSmart charge enabled, making them suitable for fast charging. The USB-C port has a maximum output of 30W, one of the most powerful, relative to its size, and capable of quickly charging a MacBook or Nintendo Switch. It supports passthrough charging, though fast-charging may be limited if you’re using two or more ports while charging.
It includes multi-layer safety features that protect against overcharging, short circuits, and current surges.
There is a four-point LED battery life display, giving a 25% range approximation for remaining battery life.
3. Anker PowerCore 26800mAh/100wh Power Bank
The Anker PowerCore 26800 mAh portable charger is another reasonably portable option. It’s not as thin as the top option on this list, but still reasonably small enough to fit into a pocket.
All three of its USB-A ports are equipped with Anker’s PowerIQ and Voltage Boost technology, meaning that it will support the fast charging of three devices at once. Passthrough charging is also available, and the battery pack can be charged even more quickly using the dual-input charging ports.
The power bank has overcharge and short circuit protection, as well as overheating protection.
The remaining battery life is indicated to within 25% by a 4-point LED display.
4. POWERADD 26800mAh 100W PD Power bank
The POWERADD 26800mAh 100W PD is one of the bulkiest of the power banks on this list and the reason why, on a list about power banks designed for portability and travel, it’s at the bottom. However, it’s still a very good choice. Charging using the 100W USB-C port as an input reduces the charging time to just 2 hours.
The USB-C port and both USB-A ports support fast charging and use a built-in chip to correctly measure the required current for your device, allowing for a past charge that will not damage your device.
It also includes an LCD display so you can check the exact amount of power left in the battery.
