Best Portable Power Banks for Charging Speed (2024)

The two I have here are the Anker Prime 20 models.

For starters, it fits perfectly in a bag or backpack, and it's well within the TSA-approved battery size limits for a carry-on.

This is a high-wattage power bank designed to keep devices of all sizes powered all day long.

It feels really solid, but it's definitely more suited as a backpack power bank.

It has the same big, glossy black plastic front, which looks pretty sleek.

The larger 250 W model does have a slightly brighter display.

For starters, it fits perfectly in a bag or backpack.

It's about 4 cm shorter than the 250 WT and lighter, but it still weighs over 500 grams, or just over a pound.

It is probably not going to fit in any GM pockets.

You can see all of the input and output from each port, and it's pretty cool to see these updates in real time.

It can get quite warm when charging something that draws a lot of power, like a laptop.

You get all these other stats, and you can see all of the input and output from each port.

So, with 10,000 milliamps and 18 watts, this is going to charge really fast, I think.

When I took this out of the box, it was reading three out of four bars, and it's still showing three out of four bars, so it hasn't been affected yet, as far as this is concerned.

I like the texture. It's thin, doesn't weigh a lot, and is about 10 ounces.

This is supposed to be rugged and somewhat shockproof, but I read that it's not waterproof.

It's lightweight, it's slim, and I can easily slide it into any of my pockets or just keep it in the backpack.

This one's light, it's fast, and it's got the trademark pilot colors, which I like. It makes it easy to find in your backpack at night.

This is supposed to be rugged and somewhat shockproof.

However, I read that it's not waterproof, so I always have Ziploc bags.

Finally, the most expensive item we have here, called the Champ Pro, also has the largest capacity, which has now been doubled again.

This device is powerful enough to supply up to 60 watts, which can also charge most laptops, including MacBooks and Chromebooks.

For a 20,000 milliamp-hour pack, it might be nice to have a second USB Type-C or USB Type-A port.

Not only is it eco-friendly, but it has also been treated to be antimicrobial.

It doesn't feel too cheap or flimsy; it's just as solid as any other power bank.

Although I will say that they don't really have a rubber accent or anything that's a little bit more grippy.

Despite its really compact size, it also remains fairly cool, even when charging things at the fastest rate.

Overall, this is still very compact for something that has a capacity of 10,000 milliamp hours.

It is going to be heavier; however, overall, this is still super compact.

This is a smart charger in the sense that it won't overheat or overcharge once a particular device, like your laptop, reaches one hundred percent.

It will stop charging on that port and continue charging on the other side if the other side isn't full yet.

Despite its really compact size, it also remains fairly cool even when charging things at the fastest rate.

This means you can charge an iPhone 13 Pro and a Galaxy S22 about three times each.

The 10,000 milliamp-hour capacity is good.

This will charge my phone roughly two times and still have some juice left over.

This item has a black carbon fiber aesthetic.

Both generations are IPX5-rated for water resistance.

It's very thin, so you're not going to notice it inside your pocket.

It is extremely small and lightweight due to the carbon fiber frame.

They both come with the same safeguards: short circuit, overcharge, over-discharge, and overheating.

Both feature the exact same ports: USB-C and USB-A.

This is a high-capacity battery charger with 26,000 milliamp hours of capacity.

The actual tested capacity of this power bank is 85% of the rated capacity, which is really quite good.

It has brushed black aluminum on the front and a nice soft-touch rubber on the back.

It is very solid, and although it feels hollow in parts, it is overall very solid and heavy.

This weighs 560 grams.

This is not something you're going to toss in your pocket to charge your phone while you're out and about.

One feature of the power button is that if you press it twice quickly, you will see a green LED at the top. The green LED indicates slow charging mode.

I prefer to use trusted brands, and I trust Anker.

This Nano Series 30W power bank has a cable permanently built right in.

The battery itself has a 10,000mAh capacity, suitable for most devices.

The device itself is made of matte plastic all around.

You do have a little bit of grooving on either side to help make it easier to grab onto.

It weighs only 7.58 ounces or 215 grams.

It's flat and very flexible, and if we roll it back, it actually acts as a natural hanging spot.

On the top, there is a button to turn on the front screen display.

The display on the front here will show you the current percentage of battery that's left.

This power bank has an incredible 24,000 mAh capacity.

300 cycles is actually quite a lot, and yes, this might be on the lower end of the industry standard.

Batteries are consumable items, and five years is a perfectly reasonable lifespan.

This is just a normal power bank; it contains lithium-ion 18650 cells.

The only thing that Anker has done is actually add a screen to it to show how many cycles it has completed.

It presumably generates a little more heat than another power bank might.

I'm here to tell you about the only power bank you're ever going to need.

I'm looking for a good Anker power bank that can not only charge my iPhone and iPad quickly but also has the capability to effectively charge my MacBook when I'm on the go.

The magnets on top of the base for the Prime power banks are really nice.

Anchor will always point out to you that you should not use the power bank after that point.

The only information I could find on this is that they say a power bank will have a lifespan of 300 cycles.

If it overheats and the internal resistance of the battery increases to a point where it's just going to explode.

The Mago 10K Slim is their slimmest wireless battery yet.

The slim model is smaller overall, but it actually has the same 10K capacity.

The new slim model is 27, making it roughly 50 g lighter.

I really like this matte white finish.

This metal band runs all the way around, and the chamfered edge provides a nice, shiny look.

It is half a centimeter thinner, making it easier to carry in a bag or pocket.

The new slim model is 27, making it roughly 50 g lighter.

We have a USB-C port on the bottom, along with some LED lights for battery status.

There's no kickstand on the back, but it does feel just a little bit lighter overall.

It is big enough to deliver serious power to laptops and tablets, while still being small enough to take on a plane.

This is the largest version of their smaller power delivery banks.

This is more for people to keep in their backpacks rather than to take it out camping.

It is designed for multi-device charging.

It is big enough to deliver serious power to laptops and tablets while still being small enough to take on a plane.

This is the largest version of their smaller power delivery banks.

No specific safety features are mentioned in the review.
