The best external batteries for the Galaxy S20: The Samsung Galaxy S20 received several notable upgrades this year, including a bigger battery. However, with a large 120Hz screen and 5G, battery life might not be as good as expected. That’s why you’ll need a Galaxy S20 external battery to keep it charged while you’re traveling or busy at work.
You can call these portable chargers, power banks, or rechargeable batteries, they all do the same thing. They store battery power that you can transfer to your phone when there is no power outlet nearby.
The Galaxy S20, S20+, and Galaxy S20 Ultra are equipped with 4000mAh, 4500mAh, and 5000mAh batteries respectively. They should be enough for the whole day, but they are not, try these power banks.
1. Anker 10,000mAh PD USB-C Charger (Best Score)
Our first choice and favorite power bank is the Anker PowerCore Slim. It’s about the same size as the Galaxy S20 and has enough battery to fully charge any Galaxy S20 model twice or more. With USB Type-C (faster) power and a regular USB Quick Charge port, you can charge your phone with any cable and it’s still fast.
2. Samsung 10k battery with wireless charging (2-in-1, wired or wireless)
If branded accessories are your thing, this Samsung battery pack can charge your Galaxy S20 with or without a cable thanks to the Qi wireless charging pad on top. This way, if you forget (or lose) your cable, you have nothing to worry about. Plus, it can also charge accessories like your Galaxy Watch 2 or Galaxy Buds , which is nice. It has 10,000 mAh of juice and comes in silver or pink for women.
3. RAVPower Pioneer 20,000mAh portable charger (large capacity)
If you’re not worried about size, for just a few dollars you can get this powerful 20,000mAh USB-C portable charger from RAVPower. This will fully charge your Galaxy S20 4-5 times, depending on the model. With 60W output and Power Delivery, it can charge your phone through any port, and it can also charge Macbook, Nintendo Switch and more.
4. 5000mAh Aukey Mini USB-C battery (Pocket-friendly)
Perfect for emergencies, this compact power bank has enough power to fully charge even the largest Galaxy S20 Ultra. The Aukey Mini USB-C battery is the size of a candy bar, so you can easily put it in your purse, gym bag or pocket and always have it on hand when you need it.
5. Anker PowerCore 26,800mAh fast portable battery (Best for S20 Ultra)
This next battery doesn’t come cheap, but the Anker PowerCore+ has a nearly 27,000mAh battery, which means it can charge just about anything you have. Whether it’s the Galaxy S20 Ultra almost 6 times, a laptop or you can charge three devices at the same time. It features USB-C Power Delivery, two regular USB ports, and even comes with its own 60W charger. This is a beast.
Or, if you want a battery specifically designed for Galaxy S20 Ultra 45W fast charging, buy this one.
6. Aukey USB-C 10,000mAh battery (thin, fast, and affordable)
Last but not least, we would like to recommend another thin, fast and affordable 10,000 mAh power bank. The Aukey PD Power Bank has enough power to charge your Galaxy S20 more than twice, supports USB-C power delivery, and has two more ports for multi-device compatibility. You can use the USB-C port, fast charging port, or a regular full-size USB port for anything else. It does a little of everything and costs less than $30.
Most won’t charge your Galaxy S20 as fast as the wall outlet that’s included, but they’re all great options. It’s still the best and fastest portable battery for charging your Galaxy S20 on the go.
