As we all know, the Samsung Galaxy S21+ and S21 Ultra are two of the most powerful smartphones on the market. But what good is all that power if your phone runs out of juice? That’s where a power bank comes in handy.
A power bank is essentially a portable charger that you can take with you on the go. They come in all shapes and sizes, and some even come with built-in cables so you don’t have to worry about carrying around a bunch of extra cords.
No matter which model you choose, a power bank is a great way to keep your Galaxy S21+ or S21 Ultra charged up when you’re on the go. In this article, we’ll recommend some of the best power banks for Samsung Galaxy S21+ and S21 Ultra.
List of 10 Best Power Banks for Samsung Galaxy S21
Power Bank Capacity and Output
When choosing a power bank for your Galaxy S21+, you’ll want to make sure to pay attention to two specs in particular: capacity and output. Capacity is measured in milliamp hours (mAh), and it determines how much power the power bank can store. Output is measured in volts (V) and amperes (A), and it determines how much power the power bank can output at once.
Generally speaking, you’ll want a power bank with a high capacity and a high output. A high capacity means that the power bank can charge your phone multiple times before needing to be recharged itself, while a high output means that the power bank can charge your phone quickly.
Power Banks with Fast Charging
When it comes to finding the best power bank for your Samsung Galaxy S21+, S21 Ultra, or another compatible device, there are a few things you’ll want to keep in mind. First, consider the battery capacity of the power bank. This is usually measured in mAh (milliampere-hours), and the higher the mAh rating, the more charge the power bank can hold.
Next, take a look at the charging speed. Many power banks now come with fast charging capabilities, which can be a godsend if you’re in a hurry. Make sure to check that the power bank you’re considering is compatible with your device’s fast charging standard (either Quick Charge or Power Delivery).
Finally, consider the portability of the power bank. Some models are quite bulky, while others are quite compact. If you’ll be carrying your power bank around with you on a daily basis, you’ll definitely want to choose a model that’s easy to transport.

If you’re looking for a rugged power bank for your Samsung Galaxy S21+, S21 Ultra, or other Android phone, there are a few things to keep in mind. First, consider the battery capacity and output wattage. A higher capacity will give you more charge cycles, while a higher wattage will allow you to charge your device faster.
