TOP 10 Best Power Banks 2024

Power banks have grown in popularity because they keep your devices charged on the go. You can find them in all shapes and sizes, and with that, they come with different price tags.

However, deciding which power bank to go for can be tricky, especially if you don’t know what to look for. They vary widely in terms of specifications, and you have to make a selection based on how you use your devices

This guide will help you choose a viable option to meet your daily demands and keep your devices fully charged at all times.

There is a range of different factors you must consider when it comes to buying a power bank. In this guide, we will briefly touch on all those points to understand what you have to keep in mind when making your choice.

Charging capacity

Different electronic devices require different power because they have various batteries that charge them. For instance, a tablet is going to need more power than a smartphone. Smartphones also vary a lot when it comes to their charging capacity because they are equipped with various batteries.

You can find the battery or charging capacity of a power bank right under the battery section. Charge capacity is measured in mAh (milliamp hours). For example, if you are looking for a 1000 mAh power bank, it means it will provide an ampere of charge for one hour.

Older phones only had 1000 mAh at maximum, but the modern phones can go around 3000 mAh like the iPhone X come switch 2716 mAh battery. Make sure to charge a device entirely; the power bank needs to have more charge capacity.

Considering this in the reference, you can understand that tablets have bigger batteries because they are powering bigger screens, so you will need a bigger power bank to charge them fully.

Outlet charge current

You will also have to look for the rate at which a power bank can deliver the charge. It can significantly influence the overall charging time.

The chargers that come with the device you are looking to charge will help you find the right charge current. Small USB devices are only capable of half an ampere charge current. Phones might take up an ampere, while tablets require up to 2.5 amperes.

Devices these days also come with fast charging capabilities, and in that manner, they can take up to 3 amperes. Therefore, this feature shouldn’t be ignored. You will find the charge current of a power bank in its specs.

If it provides a lower current, it can continue to charge for a more extended period. Larger power banks also come with multiple outputs and are written on those power banks. But such a device can never deliver the maximum current to all its outputs simultaneously.

Therefore, if you are looking for fast charging times, you need to go for a power bank that features a higher output current. If your phone cannot take that maximum current, it will only take what it needs to handle.

Ports

Older power banks only came with a single port. But it’s just not about charging your phone only. You need to charge multiple devices simultaneously, and for that, you need a power bank with multiple outputs.

You will only have to see the output current for each of these ports. Maximum output won’t flow through all these ports when you are charging multiple devices. The load will be shared among all the devices, and it will slow their overall charging time.

Weight and size

If you travel a lot and need a power bank when you’re on the go, you will need to consider a power bank’s portability. It needs to be small in size and eight so you can conveniently carry it with you.

But with a smaller size and weight, you will have to compromise on the overall capacity. The bigger and heavier a power bank is, the greater will be its charging capacity.

Lithium polymer vs. Lithium-ion

Primarily, there are two different types of battery technologies that are used in power banks. These are lithium-ion and lithium polymer. They both are very similar to each other, but they also have a few minor differences.

Lithium-ion batteries have higher power density, and you won’t have to deal with the memory effect as they become harder to charge with time. Plus, they are cheaper than their polymer counterparts.

The polymers are more durable and flexible. They are available in different sizes and shapes, and they can last pretty long. These batteries can be lightweight and can have a pretty low-profile.

Moreover, they are secure from any chances of electrolyte leakage. Some power banks mention these battery types but not all do. You will have to check their specs to get any information about their battery type.

Connectors

Many power banks come with the universal USB-A connector to connect chargers, flash drives, but modern power banks are coming with USB-C connectors, micro-USB connectors Mini-USB connectors. Some also have an Apple charger connector and lead as well.

Charging the power bank itself

You will also have to charge the power bank as well. With a bigger capacity, you will have to charge it for a longer time. If you have a 10,000 mAH power bank and pick a 1-Amp charger to charge it, then the power bank will take up to 10 hours or more to fully charge. It will take longer because of the efficiency factor of around 80%. Therefore, it will take longer than that.

Conclusion

Having the best power bank can save you a lot of headaches when they are chosen according to your needs. The most important factor to look for is high charge capacity. Otherwise, you will have to keep your power bank connected for charging, and it will damage its lifespan. Hopefully, we’ve helped you pick the best power bank for your needs.
