The Galaxy S20 has quite the big battery, but with a 120Hz screen and 5G radios inside, you never know when your day will go into overtime and you'll need to reach for a portable charger to keep your Galaxy S20 alive. (Or, y'know, you need a power bank on the way to work because you forgot to throw it on the charger last night the way I did). Never fear, power banks are here and they can charge our S20s three different ways this year.
Best overall
AUKEY Wireless Power Bank with 18W PD (10,000mAh)
Staff pick
Roughly the same size as the Galaxy S20, this 10,000mAh bank can recharge even the S20 Ultra twice before it runs dead. It supports Power Delivery, QuickCharge 3.0, and 10W Qi charging so you can charge however you want.
Top speed for S20 and S20+
Samsung Super Fast 25W Portable Wireless Charger (10,000mAh)
This power bank supports 7.5W wireless charging so that you can top off accessories like your Galaxy Watch or Buds, and it supports 25W fast charging via USB-C for the S20 series, meaning you spend less time plugged in.
Pocket-friendly
RAVPower PD Pioneer 10,000mAh 29W Portable Charger
This compact power bank is like an extra-fat Snickers that can recharge your S20 twice via USB-C Power Delivery or QuickCharge via USB-A. It's available in black or white, and also comes with a C-to-C cable.
High capacity
Zendure A6PD 20,100mAh PD Power Bank
This might be overkill for an S20, but if you want to charge a laptop or three phones at the same time, Zendure's power bank has 45W charging for laptops and an 18W QuickCharge 3.0 port.
Value pick
Xcentz USB-C Power Bank 5,000mAh PD
Honestly, most times when we go out, we only need to recharge our phones once at the most, so this 5,000mAh bank is a perfect size. I also love the pastel colors available like pink and teal.
Best for Ultra
ELECJET PowerPie 20,000mAh Power Bank
The S20 Ultra supports 45W charging under very, very specific conditions, and the PowerPie is one very few power banks that actually meets all of them. You can also use it to recharge tablets and USB-C laptops.
Slim stability
Anker PowerCore Slim 10,000mAh PD
Anker makes dependable chargers that can take a beating and keep running for years and years. This phone-sized model is a little more expensive than Aukey's, but it looks a little better too with that patterned back.
Luxurious look
iOttie iON Wireless Go Power Bank (10,00mAh)
Metal and plastic power banks may seem slick, but covering them in a plush fabric is ten times better! There are still two wired charging ports in addition to the Qi pad, and you can get it in gray or that lovely heart red.
Smaller than a credit card
Zendure SuperMini (10,000mAh)
Despite being half the size of the AUKEY and Samsung 10,000mAh batteries, this 18W power bank will charge your S20 via USB-C or USB-A. It'll also fit in super tiny purses and pockets.
The best Galaxy S20 portable chargers let you charge your way
There's a couple of ways you can charge your S20, but the most important things to look for will be Power Delivery (PD) and Qualcomm QuickCharge (QC). While Samsung supports Power Delivery, the S20 is capped at 15W with most PD chargers, and most QC ports aren't rated much if any higher on a power bank, anyway — that comes into play more with wall chargers.
What does this mean? Charge with whatever standard and cable you have on hand; they're both going to charge your S20 at a good speed, even if it might not be the 25W you'd get with the Samsung wall charger. The is my favorite because that almost phone-sized form factor makes it easy to carry in your pocket next to your S20, and it's got wireless charging on top of PD and QC. The can wirelessly charge your S20 and your Qi-enabled wireless accessories, like those swanky new Galaxy Buds, and it comes in a soft pink that should complement the Cloud Pink S20 quite well.
