How to choose an Anker backup battery

Backup batteries must be so familiar and necessary. And among many brands, Anker is always a bright name at the top you should own.

To choose the most suitable Anker backup battery, you can refer to the criteria below.

Check battery capacity

The first thing you need to do is check the product’s battery capacity. This will help how many times the phone charges.

Battery capacity depends on each person’s needs.

1. Compact, easy to carry from 3000mAh

Depending on your usage needs, choose to charge your phone 2 or 2 times. You should choose one with a battery capacity of 3000mAh.

The size of this product is usually compact and lightweight and can be used when the phone suddenly runs out of battery during travel.

The product is also easy to carry for backup charging every day.

2. For larger usage needs, choose from 10,000mAh

If needed, use it on a variety of devices and frequently. Normally, you can charge your phone 3 or 4 times.

This is also the popular capacity of Anker backup chargers.

Often watching games, watching videos, and navigating, the phone battery will run out very quickly. Therefore, if you need to charge every day, then choosing 10,000mAh is quite reasonable.

3. High capacity about 20,000 mAh

Backup batteries with a capacity of 20,000mAh or more can often be used for laptops. Suitable for those who work and charge devices on the go or in places without sockets.

In addition, a smartphone can last up to 7.8 charges. Extremely convenient when using on trips or sharing rechargeable batteries with many users.

Check the number and type of charging ports

You need to pay attention to the number of output ports of the backup battery. If you need to charge multiple times, you should choose 2 or more ports.

The output port charging type must also be compatible with your charging cord. Some Anker backup batteries have a USB-C port that can be compatible with many different types of devices.

Note when using Anker backup batteries

Has battery level display

Anker’s backup battery is equipped with LED lights, so you can easily monitor the remaining battery power. Avoid the situation where the backup battery runs out of battery right when you need to use it. Therefore, it is recommended that you buy a backup charger that displays the battery level for easy observation and monitoring.

Choose a PowerIQ device from Anker

This technology will allow you to automatically identify connected devices, applying the maximum current appropriate to that device, for the fastest charging speed.

If you want to charge any device with fast functionality, choose PowerIQ 1.0. The device’s output/input reaches a maximum of 12W.

If you need the device’s charging speed, you should choose the PowerIQ 2.0 version. Will allow device charging with up to 18W input/output.

Pay attention to style

Anker’s backup battery has a quite convenient design, easy to hold. In addition, it also has a quite thin and light design. Therefore, you should choose according to your needs and preferences.

Slim backup batteries are an option for those who want to charge and use their phone at the same time. If you use it for sitting at work or in places without an outlet, you can choose a backup battery with a larger size.

Note when using Anker backup batteries

Below are some notes when using Anker backup batteries.

Do not leave the charger plugged in for a long time

If you leave the power bank plugged in for a long time, it can damage battery quality and pose a risk of fire and explosion.

And now there are also many types of backup chargers equipped with LED lights to signal the battery level or automatically turn off the power. However, you should stop charging immediately after the battery is fully charged.

Charging speed is too slow

If charging your power bank feels too slow, it’s usually because the output of the charger and the AC adapter are not compatible.

And Anker recommends that you use a USB charger with an output of 5V/2A or higher, to make the battery charging process more efficient.

Which Anker backup battery should I choose?

Depending on each person’s needs and preferences, choose which Anker backup battery is right for you.

And when I use it, I like the ANKER PowerCore Select 10000mAh backup battery line.

Because the compact, smart design is very convenient because it can be carried anywhere, this is the first point that I like.

In addition, the price is cheap with moderate battery capacity suitable for your usage needs.

I use it quite durable so I don’t have to change it constantly.

The above are just my assessments, so to choose the most suitable product, you should rely on your own needs.
