Charging your phone is still a daily task, so you might as well figure out a way to make that more efficient. Unchain you and your Galaxy S9 from wall outlets by getting a portable charger. These accessories allow you to charge your phone from anywhere at any time. It’s convenient, and you’re not spending a fortune for that. All you do is connect your phone to a standalone battery and the juice starts flowing.

Here are some of the best portable chargers for the Samsung Galaxy S9 and S9+.

Samsung Fast Charge Portable Charger (5100mAh)

  • Price: $40, eligible for Prime shipping
  • Color(s): Navy Blue, Silver

Portable chargers are neutral accessories. That means you can use pretty much any phone or tablet with them. But you might be someone who likes first-party accessories to keep everything in the family. If you own the Galaxy S9, perhaps you should own Samsung’s portable charger. The company released a new version in recent months that pairs perfectly with its latest flagship.

As its name suggests, this portable charger with a 5100mAh unit features fast-charging capabilities. The accessory also has a carrying strap, an LED power indicator, and a micro-USB cable that includes a USB-C adapter. When it’s time to charge the accessory itself, you’ll be using a USB-C connector just like if you were charging the Galaxy S9.

RAVPower Wireless Portable Charger (10,400mAh)

  • Price: $68, eligible for Prime shipping
  • Color(s): Black

RAVPower’s wireless portable charger is one of the best accessories around because you’re getting two major qualities in one. The portable charger aspect enables on-the-go charging, and the wireless aspect removes the need for any wires. Just place the Galaxy S9 on its surface and you’re instantly sending power where it’s needed.

Two big advantages are here. First, RAVPower packed a 10,400mAh battery inside. That’s enough to charge Samsung’s Galaxy S9 around three times. And it’ll also charge your phone very fast. The 10W speeds are comparable to what you get out of a stationary wireless charger.

Pricing could be better, but you’re picking up an extremely useful accessory from a reliable brand.

Jackery Bar w/ LED Flashlight PortCharger

  • Price: $17, eligible for Prime shipping
  • Color(s): Black, Silver, Gold, Orange

Jackery created a portable charger that has a modest battery inside. The 6000mAh unit should get you two uses on a single charge of its own, which is a sweet spot that affords the compact design. But there’s an extra feature you might come to appreciate at times. Next to the micro-USB and USB ports, there’s actually an LED flashlight. So you’ll get to charge your iPhone but also see your surroundings if the lights go out.

Anker PowerCore+ Portable Charger Bundle (26,800mAh)

  • Price: $100, eligible for Prime shipping
  • Color(s): Black

Anker’s PowerCore+ series comes in the form of a portable charger, and it’s among the strongest you’ll find. The 26,800mAh battery provides enough juice through two ports to charge any mixture of phones, tablets, and more. It could even charge your laptop, assuming it has a UBC-C port for charging.

Before you lose your mind over the price, recognize what you’re receiving with this bundle. It’s not just a portable charger. Anker is including a 30W USB-C wall adapter as well. Most brands give you the portable charger and wave goodbye, but Anker makes sure you have something to actually charge the main accessory with. Both the portable charger and the wall adapter also boast blazing-fast charging speeds; therefore, you know you’re getting the best flow of power possible.

Anker also throws in a micro-USB cable in addition to the standard USB-C cable if you want to charge an older device.

Xiaomi Mi Power Bank Pro (10,000mAh)

  • Price: $30, eligible for Prime shipping
  • Color(s): Black

Its products aren’t available everywhere, but Xiaomi does sell the Mi Power Bank Pro in North America. It’s a 10,000mAh portable battery that includes the qualities you need from an accessory like this. Xiaomi uses a double-anodized aluminum exterior to protect the high-density battery inside despite the entire body measuring just 0.49 inches thick.

Each time the portable charger is at full capacity, you should be able to charge your Galaxy S9 a smidge under four times.

Xiaomi also put the Mi Power Bank Pro through a significant number of tests. The company worked to implement nine layers of “world-class circuit chip protection” involving temperature and overvoltage. You paid a lot of money for the Galaxy S9, so don’t leave it vulnerable to damage by going with an unreliable brand and accessory. The Mi Power Bank Pro is strong, and it’s not too expensive.
