Top 10 Best Portable Chargers [2024]

If you often find yourself running out of charge whilst you’re out and about, then getting a portable charger could be exactly what you need. A portable charger can help to keep your phone and other devices charged whilst you’re away from home, so you won’t have to worry about conserving your battery life.

What To Look For in a Portable Charger

Size and Weight

Depending on how you plan to carry around your power bank, it’s important to think about what size and weight would be ideal for you.

If you’re thinking about carrying it around in your pocket, a smaller size would be the best choice. This way, it will sit comfortably in your pocket without falling out, and it won’t feel too heavy after a while of carrying it around. Plus, smaller size is perfect if you commute mostly on foot.

Unfortunately, having a smaller-sized charger is not great if you need a larger capacity, and it may only be able to charge a small number of devices at a time.

A larger-sized portable charger is likely to have a higher capacity and more charging ports that allow it to charge multiple devices at the same time. This size can fit nicely inside your bag, which will make it easier to carry, but it may feel heavier after a long day.


A portable charger’s capacity can determine how much power it can provide before it needs to be refueled. For example, if your phone battery size is 3,000mAh (milliampere-hours), then a 3,000mAh portable charger/power bank will almost be able to charge it fully.

For it to be fully charged, you will need a higher capacity to make up for any power lost through circuit resistance, conversion, and the quality of the charging cable.

If you need to charge multiple devices on the go, you should consider a power bank with a higher capacity. One of the highest capacities available on the market is 20,000mAh, with some models available with an even higher capacity, perfect if you need to charge more than one device.

However, a higher capacity means that the size and weight will be bigger, which can affect its portability, so it’s important to think about whether a larger size will benefit you.

Input Current

The input current of a portable charger/power bank affects how much time it takes for it to fully recharge itself. Most power banks have an input current range between 0.8A to 1.5A, depending on their capacity.

A portable charger with a higher capacity rate will take longer to fully recharge than a portable charger with a smaller capacity rate. It’s best if you recharge your power bank overnight so that it will be ready for the following day.

If you don’t have time to wait for the portable charger to fully recharge, or if you’re running on a tight schedule, it would be best for you to thinking about getting a model equipped with a high input current for a shorter recharge time.

Number of Ports

The number of ports on a portable charger can determine how many devices can be charged at the same time.

Usually, lower capacity power banks will have at least two USB ports available, with higher capacity power banks being equipped with more. You’ll often find that a power bank with a big price tag will have a higher number of charging ports.

If you’re looking at having more than two charging ports, it’s important to consider the total output current. A power bank with two available ports that are rated 2A/5V means that each port will receive 1.5A in output if they are both being used. This is considered a slow charging rate, so your devices will take longer to be fully charged.

The higher the total output rating, the faster the charging rate will be in all of the available ports. So, if you’re looking at having multiple charging ports with your portable charger, then you should consider getting a model with a high total output current in order to achieve faster charging times.

Quality and Durability

It’s very important for a portable charger to be high-quality and durable. This is because they are batteries and must always be treated with care.

A power bank being sold for a lower price is likely to have been made with low-quality materials and may not include any safety measures. The lack of temperature control and short circuit preventions can put you in a dangerous position as there is a huge risk of explosion. If the price seems too good to be true, avoid that power bank at all costs.

To ensure that your power bank is of high quality and is safe to use, you should buy them from reputable brands. The following portable chargers feature high standards and are from trustworthy brands so that you can stay clear from unsafe products.
