Anker’s well known for its lineup of power solutions, so it comes at no surprise that the Anker Prime 20,000 mAh power bank tops our list of best portable chargers. With its generous battery capacity, it’s more than capable of charging small stuff like your phones and wearables — but it’s also powerful enough to charge laptops too.

What makes it better is that it features a maximum charging speed of 200W, which is ridiculously fast if your device can support it. For fast charging phones, it could take 30 minutes or less to get it back up to 100% capacity. Meanwhile, the unit itself charges at a speedy rate of 100W. There’s also a handy display that shows its charging capacity and the actual speeds it’s charging with its USB ports.

Not the fastest to a full charge

Although it might not be as familiar a brand, the INIU 10000 mAh charger is the best budget portable charger with its affordable cost. You won’t spend a whole lot picking it up either, since it frequently gets discounted to get it down to around $20, which is super cheap compared to the other options.

This INIU charger stood up in 15-minute and 1-hour timed charging (at 22%, 78%), with times that were within 1-2 percentage points ahead of what we got out of comparable Anker PowerCore Slim's times. Even with its ultra affordable cost, we’re glad that INIU offers a 3-year limited warranty — which is more than the usual 1-year that other battery bank makers offer.

There’s something to say about MagSafe. It lends a helping hand with the mophie Snap+ Juice Pack Mini in keeping it fastened snugly on the back of a compatible iPhone with MagSafe for on-the-go charging. That way, you can always have it on hand — even when you need to top it off while waiting for your coffee in the morning.

With its 5,000 mAh battery, it’s able to provide nearly a full charge to most iPhones, but there’s also a USB-C port on hand to charge other phones and gadgets.

However, its value in being a portable charger for travel is its unique ability to jumpstart a dead car battery. The last thing you need to worry about while traveling is a disabled vehicle, but you can save yourself time and heartache by bringing it back to life with the Scosche PowerUp 600.

Can't replace integrated cord

Versatility is what the Anker Power Bank Fusion 10K is all about. That’s because this portable charger from Anker doesn’t force you to bring along other cables and adapters to use it. With its integrated USB-C cable, it packs 30W wired speeds that’s fast enough to power some laptops in addition to phones. You can also lean on its other USB-C port to charge another device simultaneously with its 10,000 mAh battery cell.

Recharging the Anker Power Bank Fusion 10K is also a cinch because it features a built-in foldable charger when the battery itself needs to be recharged. With this setup, you might not even have to worry about bringing any of your chargers and cables because it conveniently packages everything into its design.

How to choose the best portable charger

Finding the right charger capacity: You'll often see a four to five-digit number, with the letters mAh following it, and that's your first big indicator of how much this charger is right for you. If you're constantly refueling your phone and other gadgets, go for at least 10,000mAh. For each extra device you charge, add at least 5,000 to the mAh rating you're looking for. Just need to prevent your device from hitting 0 on late nights out? You'll be good with something in the under 5,000 mAh rating, provided you remember to charge it often.

Be a ports authority: If you hold onto your devices forever, and don't already know what a USB-C port is, you can probably just get whatever fits your price. But if you're the kind who wants faster charging, look for a brick that has PD in its name. The best portable chargers, at least for my money, charge devices the fastest and use the Power Delivery (PD) standard. Also, their USB-C ports mean you can refuel these power banks with the same cords used to charge modern laptops.

How we test the best portable chargers

You want a charger that was put through the rigors of refueling, so we did just that. With timers in hand, we kept draining an iPhone 15 Pro and then timed how much time it took for each power bank to refuel those phones. Along the way, we checked out how much of said iPhone 15 Pro (the same one) were refueled after 15 and 60 minutes. We kept that iPhone at 100% brightness the whole time.

Our ranking also factored in the portability and designs of each model, as especially small and pocket-friendly chargers can't physically store as many mAh of battery power as their larger brethren. Similarly, the smaller a charger is, the less likely it has more than two ports (one for gaining a charge, the other for giving power).

    Best power banks and chargers of 2023? And most of them only output USB A?!

    This article was either done by a bad Ai, written within 5min by someone who searched for the most bought battery banks on Amazon, or reused from several years ago.

    The "best portable charger" is not a 10,000mAh USB-A 15W charger for $20, that's just one of the most purchased on Amazon.

    One of the best portable power banks is going to be the Anker 737 or the Ugreen 145w. They both feature two type C outputs and one type A output, the Anker 737 being able to output up to 140W compared to Ugreen maxing at 100W. Anker has a 24000mAh battery and PD3.1 complaint and Ugreen is 25000mAh with PD3.0; they both are compatible with all charging standards.

    These might be a bit overkill for the general user, but they are among the best, if not the best portable power banks.
