Best Power Banks for Samsung Galaxy S9 in 2023

(Last Updated On: September 18, 2023)

It’s another year, and another Samsung Galaxy smartphone has been released. The Samsung Galaxy S9 is here. Quite a few things haven’t changed, but at the same time, no matter how you put it, it’s an improvement from the previous Galaxy S8 in small ways. It has better specs with it using the new Qualcomm 845 Snapdragon processor, and this time around, the Galaxy S9+ has 6GB of RAM rather than just having the two models having the same amount of RAM. One significant improvement is the camera because the Aperture on the Galaxy S9 can change.

With that said, if one thing hasn’t changed, it’s the battery power from the Galaxy S9 and Galaxy S9+. The Galaxy S9 still has a 3,000mAh battery, and the S9+ has a 3,500mAh battery. The problem with that is that the two smartphones have better specs than before, which also means they consume more power. So, the use of a power bank is more important than ever. You’re going to be using the S9 quite heavily with its buttery smooth performance, but using the S9 heavily will burn into the battery quite quickly.

That’s why we chose the best power banks for the Galaxy S9 so you can charge this new Samsung smartphone at its max charging speed and to full power while you’re on the move.

iWalk LinkPod USB-C Mini Power Bank

The first power bank I want to recommend for Galaxy S9 is this iWalk LinkPod USB-C mini power bank. The charger is tiny because it has a 4,800mAh battery that can charge up the S9 to full power about once; after that, you will have to recharge the power bank. This power bank has a built-in USB-C connector that can output 18W, so you can fast charge your Galaxy S9, and you don’t need a cable to use this power bank at all. You can recharge this power bank simply by plugging the USB-C connector into a USB-C wall charger.

However, you can also use the USB-C port to recharge this power bank with an 18W recharge rate, and a USB-C to USB-C cable is included in the box. At the front of the power bank is a digital capacity display with a power button off to the side.

iWalk LinkPod Y2 Built-in USB-C Cable Power Bank

Another iWalk power bank I want to recommend is this LinkPod Y2 charger. This charger has a 9,600mAh battery capacity, higher than the previous iWalk power bank, so this one can charge your Galaxy S9 to full power about once and possibly twice if there is enough spare capacity. Charging from this iWalk power bank is done via the built-in USB-C cable, and it has an 18W charging speed, so you can use it to fast charge your S9; furthermore, the built-in cable can be used to recharge the power bank by plugging it into a USB-C port on a wall charger.

You also have the option to recharge this LinkPod Y2 power bank from the USB-C port, and it also has an 18W recharging speed. A USB-C to USB-C cable is included in the box, and the battery capacity is shown at the top of the power bank.

INIU B2 15W 10,000mAh Power Bank

This INIU power bank is simple, but it’s still great for charging your Galaxy S9. The power bank has a 10,000mAh battery capacity that can charge Galaxy S9 or S9 Plus to full power about two times. The highlight of this power bank is that it comes with three special cables: a Micro-USB to USB-C, a Lightning to USB-C, and a USB-C to USB-C cable. These cables can be input into the middle USB-C port on the power bank, and then the other end can be inputted into a compartment, letting the cable become part of the power bank.

These special cables make portability easier with the power bank. On the charging side, there are two USB-C ports and a single USB-A port; the max output of the power bank is 15W, so if you want to fast charge your Galaxy S9, I recommend charging it alone. The max recharge rate is also 15W. The power bank has a touch-sensitive button at the top that activates the screen to show the remaining battery capacity.

ROMOSS PEA30 30,000mAh Power Bank

This ROMOSS PEA30 power bank has a massive 30,000mAh battery capacity and a 30W max output. So, if you want to charge your Galaxy S9 a few times to full power without needing to recharge the power bank, this is the power bank to choose. The charger can output 30W of Power Delivery from the USB-C port, with two USB-A Quick Charge ports. You can fast charge your Galaxy S9 from any port on this power bank.

Recharging is accessible because the power bank has three input ports you can use one at a time; the USB-C port can also be used as an input, and there is a Micro-USB and Lightning input ports. I recommend recharging via the USB-C port because it has a 30W recharging speed, and you’ll need a fast recharge rate for a 30,000mAh battery capacity.

MOMAX 10,000mAh 20W Aluminum Power Bank

This MOMAX power bank stands apart from other 10,000mAh capacity ones mainly because it’s made of Aluminum and has a 12mm thickness that can easily fit into your pocket. With the size of this power bank, you wouldn’t think that it has a 10,000mAh capacity that can charge up your Galaxy S9 to full power about two times.

The MOMAX power bank has a 20W USB-C PD port and USB-A Quick Charge port, so you can fast charge your S9 from either of the ports. To recharge the power bank, you can either use the USB-C port to recharge the power bank at 18W, or you can use the Micro-USB input, but that has a 10W recharge rate.

MOMAX 10,000mAh Wireless Charging Power Bank

Another MOMAX power bank I want to recommend is this wireless charging one. This charger also has a 10,000mAh battery capacity, a 20W Power Delivery USB-C port, and a USB-A Quick Charge port. So you can fast charge your S9 from either of the ports on this power bank and charge your S9 to full power about two times.

The main difference here is that there is a wireless charging pad at the top, and you can use that to charge your S9 at 10W wirelessly. Also, this power bank has a Lightning input port. However, I recommend recharging via the USB-C port because it has an 18W recharge rate.
