Best Power Banks for Samsung Galaxy S20, S20+, S20 Ultra

The Samsung Galaxy S20 is here and with it comes for three different models, and three different battery sizes to go with them. The S20 has a 4,000mAh battery, which we thought was large, but now that’s normal. The Galaxy S20+ has a tad larger 4,500mAh battery. Then the Samsung Galaxy S20 Ultra has a 5,000mAh battery, which is huge.

These larger batteries are great, but they’re here for a reason and that would be to accommodate the higher specs that these phones have. Such as the new Snapdragon 865 processor, 12GB of RAM or a 16GB RAM option for the S20 Ultra, and a 120Hz screen that can tend to drain battery power. There’s a high chance that many people are going to use the 120Hz screen refresh rate setting as its so smooth to use.

With all that, using a power bank for your new Samsung phone can be important for when you’re running low on power out there. We’ve compiled a few power banks that you can use to fast charge your S20 and keep it all full charge for either one day or a few days.

Power Banks in this Guide:

Anker PowerCore Slim 10000 PD

This Anker power bank has a 10,000mAh power capacity. A 10,000mAh power bank is what you’re going to want to aim for when it comes to getting a power bank for your S20 since each of the models have such large batteries.

So with this PowerCore Slim, you can charge the S20 and S20+ to their full power about two 1.5 times. When it comes to charging the S20+, you’re going to get a single full charge and some power left over.

The charging is done through two ports. One is a USB-C Power Delivery port with an 18W charging speed, pretty good for fast charging your S20. The other port is a USB-A port with a 12W charging speed. This power bank can also be recharged at Power Delivery speeds when you use a PD wall charger, but this power bank does not come with one. We recommend Anker’s very own PD wall charger for faster recharging.

A non-power related reason to get this power bank is for its form factor. The charger has a length of about 6 inches and a thickness of 0.6 inches. Making it easy to slide into a pocket.

Anker PowerCore+ 26800 Power Bank with 30W Power Delivery Charger

Power banks with a 26,800mAh power capacity might seem overkill for charging your S20.

However, they may not so overkill if you want to be able to charge your Samsung Galaxy S20 multiple times throughout the week and not have to recharge the power bank. That’s what this Anker PowerCore+ features, because with its 26,800mAh power capacity you’re able to charge a base S20 and S20+ model to full power about 5.5 times.

This Anker power bank also has a 30W USB-C Power Delivery port that can charge your S20 faster than an 18W PD port. The other two USB-A ports share a 15W charging speed.

Also, included is a 30W Power Delivery wall charger and a USB-C cable, you can use both to recharge the power bank faster, and use them to fast charge your Galaxy S20.

Zendure A6PD 20,100mAh 45W PD Power Bank

Zendure A6PD 45W 20,100mAh Power Delivery Portable Charger

Bringing the power capacity back down, this Zendure power bank is still enough to charge your Galaxy phone to full power about three times.

The charging power is higher than any of the other power banks that we’ve mentioned because the USB-C PD port outputs 45W. A massive charging power that can be used for fast charging your S20 and can be used for charging Power Delivery laptops like an Apple MacBook or Chromebook.

The other output port on this charger is USB-A port that uses Quick Charge, and you can also use that port to fast charge the S20 while you’re charging a laptop with the PD port.

To recharge the power bank you can either use the PD port or the Micro-USB input port. We recommend using the PD port for recharging because you can recharge it at 45W with a PD wall charger, but a wall charger is not included. The Micro-USB input port only has a 12W recharge speed.

Xcentz 5,000mAh 18W Power Delivery Power Bank

For a 5,000mAh mini power bank, the charging is impressive, and that’s because this power bank uses an 18W Power Delivery port and a Quick Charge USB-A port. You can recharge the power bank at PD speeds with the USB-C port, too. There are not very many power banks within this range that are capable of this charging power.

Of course, the other impressive part is the form factor. As this charger has a length of 3 inches, and a width of 1 inch, you don’t have any excuses on why you can’t take this charger anywhere and everywhere.
