If you are planning to buy a power bank for your tablet or smartphone, this guide will help you pick the right size power bank for you.
You can stop your phone, tablet, or laptop battery from depleting quickly, and there are fixes for this problem. But not everybody is willing to make concessions. That’s why portable power banks or battery packs exist.
Ever wondered what the best capacity for a power bank is? Like our smartphone batteries, capacity is typically measured in mAh (Milliamp Hours). The capacity increases with the size of the number. With that in mind, we will assist you in focusing your search on a portable charger that suits your specific lifestyle and power requirements.
Features to Consider When Looking for a New Power Bank
When purchasing a power bank, you have a wide range of options, so it’s crucial to comprehend the distinctive features of each one so that you can be certain to get the ideal power bank for you.
Number of Devices
How many devices do you intend to charge each day on your power bank, first? Just your smartphone, then? It is a good idea to have a backup plan in case something goes wrong.
If you plan to refuel your wireless headphones/earphones or your watch, you are in the safe. This is because these devices do not eat much of the stored energy compared to other power-hungry devices like tablets and laptops (yes, some laptops charge via power banks and vice versa).
The Capacity You Need for Your Power Bank
The power bank’s capacity is the most straightforward feature to think about. Simply put, the more mAh the power bank has, the more power it produces. The mAh value is an indicator of the type of power bank and its function:
- Up to 7,500 mAh – Small, pocket-friendly power bank that is usually enough to fully charge a smartphone from once until 3 times.
- 7,500- 14,999 mAh – A medium power bank, small enough to fit in your jacket pocket, can typically charge a smartphone four to five times.
- Large power bank with a capacity of more than 15,000 mAh, which can typically charge a smartphone five or more times in full. These are transported in a bag due to their size.
If you’re looking for a more compact power bank, you might have to give up some power because typically, the higher the mAh, the bulkier the power bank. In addition, if you intend to use your power bank for travel, keep in mind that any power bank with a capacity greater than 27,000mAh cannot be brought on board any aircraft and may be seized at the airport.
Check for a Power Indicator
You can monitor your power bank’s charging progress with the aid of a power indicator. Small LED lights are the typical form of this. This feature is often overlooked, but it is one of the most important ones to consider when looking for a new power bank.
Which Power Banks Are Allowed on the Plane?
If you’re going on vacation and want to take a power bank on the plane, it can only have a maximum rating of 100-watt hours (Wh). It is simple to calculate by multiplying the result of the division of milliamp hours (mAh) by 1000 and voltage (V). With the airline’s approval, larger power banks may be transported.
Here is what you should know about traveling with your power banks and batteries:

Charging Speed of the Power Bank
Even if you opt for a bigger and heavier power bank, you should check the fast charging capability. After all, you wouldn’t want your smartphone to be permanently attached to the power bank for extended periods of time. USB-C Power Delivery is supported by some power banks, including the Romoss SW30PS+.
Some include Quick Charge 3.0 support as well. These guarantee a quick and efficient charge for your compatible phone. This one ensures that phones like the iPhone charge at 18W while some Samsung flagships charge at around 25W.
