How to Choose the Best Battery Backup for iPhone?

Choosing the best battery backup for your iPhone and tablet will depend on your needs and charging requirements. For example, if you want to charge only an iPhone, a battery backup with a lower capacity would work great. However, if you're looking to charge multiple appliances at the same time, a power bank with multiple output ports should be worth considering.

Here are some of the factors to keep in mind while selecting the battery backup for iPhone 14 Pro or other models.

Capacity: If you need a few extra hours of power, a small and portable power bank with a small capacity will suffice. On the other hand, if you want to stay charged for a full day or more, you'll need a larger battery backup with high capacity. It's important to choose a power station with a battery capacity that exceeds the wattage consumption of the appliance you're planning to charge.

Size: If you use it daily, you want a reliable, durable, and lightweight option. It should be easy to move so that it can be transported from one place to another easily. Jackery Explorer Portable Power Stations are lightweight and portable, making them easy to move. For example, the Jackery Explorer 100 Plus Portable Power Station can fit right in your palm and can charge all iPhones.

Safe: The battery backup for the iPhone should not emit any harmful toxic gases, thereby making it a great option for both indoor and outdoor use. The Jackery Explorer Portable Power Stations have an in-built battery management system that ensures safe charging of all the appliances.

Long Battery Life: Generally speaking, the batteries with LiFePO4 or NMC battery types have a longer lifespan. They can last for 10 years with minimal maintenance.
