Power banks look pretty simple but they’re anything but that. It can be confusing to understand the specs of a power bank when you’re purchasing one for the first time, especially the numbers that outline their capacity.

The best power banks we have tried have all come from Anker, but that doesn't mean Anker is the only brand you should consider. All of the power banks on this list passed our testing, traveling with us on the road and powering our devices at home. Anker is the best, but these batteries from Baseus and Otterbox performed well. Meanwhile, a 10,000mAh battery can give today’s flagships two full charges. A 20,000mAh battery can charge a flagship four times, or two phones two times. Some power banks have enough juice to power laptops. Of course, a higher capacity often translates to a heavier, larger, and more expensive battery. If you’re a long session angler or someone that needs a power bank for a variety of electronic items, then this is a fantastic choice. It’s still pretty lightweight and extremely robust, so it’s not a huge burden to bring along (gone are the days of the rigged-up car battery power bank). The most important question to consider when buying a power bank is what will you be charging? If you are charging a small smartphone and that's all, a simple power bank will suffice.

This will provide you with all the power you could ever need for a carping holiday or long session on home soil.

You need fast power: This is a very slow charger, whether wired or wireless, so it's better for casual charging while you sip your water and read a book. That means I could twist my phone sideways into landscape mode and use the Baseus power bank as a portable stand for Apple's new StandBy mode, which is one of my favorite features on iOS 17, and certainly the one I use the most often. So what’s the sacrifice for all this power? Well, this RidgeMonkey vault is definitely a little bit bulkier and a bit heavier, weighing in at around 1.5 kilograms. However, that really is nothing when you consider how much capacity you get. The number and type of devices you need to charge as well as the length of your sessions will affect how big a power bank you need.The bottle is actually a nice, insulated affair, and it kept ice in cold water for 12 hours, which is all that we need.

This allows you to charge everything from phone, camera, and tablet batteries while powering 12v appliances (within reason) such as a camping refrigerator.

Everybody on our gift list who got a new iPhone is going to get an Anker Nano Power Bank (22.5W) this year. This cute little charger is perfectly sized to sit beneath your favorite smartphone, plugged into the USB-C port with a little plug that opens out or hides away for a sleek look. Anker batteries also look great and are built with high quality parts.

It's easy to set up a phone to charge while studying, working out, or working away from home: all places we take a water bottle and need a full phone battery.For most, a simple power bank of around 25,000 to 30,000mAh will suffice. This kind of size is ideal for casual anglers that don’t head out for more than a few nights at a time.

Although I say this is a great power bank for shorter sessions, it can still charge a high-end smartphone from 0% to 100% around 5 to 6 times before being completely drained. That’s pretty impressive.

That saying this thing really is a beast, If you’re planning on a week long trip to the continent or a longer weekend session filming on the bank the Powapacs Atom 78 is the power bank you need to stay connected and fully charged.Next, you should ask yourself how many outputs you need on your power bank. How many electric devices do you bring on a typical session and how many will you need to charge at the same time? The capacity of a power bank is the most important aspect to consider before purchasing one to use while carp fishing. Our favorite power bank has a 10,000mAh battery, and the Samsung Galaxy S23 Ultra has a 5,000mAh battery, so the math should be simple, right? It charges twice. Except that's not how it works. Power banks are not 100% efficient, and even though you start with plenty of power, a lot of it is lost in the charging process.
