Power banks: How to use and care for your portable lifeline safely
Counterfeit or cheap knock-offs often lack essential safety features, and reports of power banks overheating or catching fire have increased in recent years due to these unsafe products.
In today’s digital age, a power bank is essential for staying connected on the go, ensuring your devices remain charged whether you’re commuting, travelling, or out and about.
But like any battery-powered device, power banks need proper care to perform well and last long.

With a few simple habits, you can ensure your portable charger remains safe, reliable, and efficient for years to come.
1. Understanding your power bank
At its core, a power bank is a rechargeable battery designed to store energy and transfer it to your devices when needed.
Most use lithium-ion technology, similar to what powers your phone, but with larger capacity.
These devices vary widely in size and capacity, from compact models that fit in your pocket to larger ones capable of charging laptops.
While power banks are convenient, they are not invincible. How you use and maintain them can make a big difference in their lifespan and safety.
2. Smart charging habits
The first step to protecting your power bank is charging it properly.
Always use the original cable that comes with the device or a high-quality certified replacement.
Cheap or damaged cables can lead to inconsistent charging and even damage your power bank or your devices.
Avoid leaving your power bank plugged in long after it reaches 100 per cent charge.
While most modern devices have built-in safeguards to prevent overcharging, extended charging times can generate heat, which slowly degrades the battery cells.
Also, resist the temptation to let your power bank completely drain to 0 per cent. Lithium-ion batteries perform best when they are kept charged between roughly 20 per cent and 80 per cent.
Avoid using your power bank to charge a device while it is plugged into the wall socket.
Unless your power bank is specifically designed for this, it can cause overheating and damage both the power bank and your device.
3. Keeping your power bank healthy
Proper storage and maintenance are just as important as smart charging.
Always store your power bank in a cool, dry place. Extreme temperatures, especially heat, can cause irreversible damage.
It is also important to never leave your power bank inside a hot car or exposed to direct sunlight.
Regularly check and clean the USB ports to ensure good connections.
Avoid dust, lint, or moisture, which can cause poor charging performance or even short circuits.
A gentle brush can keep ports clean and functioning smoothly.
And if you do not use your power bank often, be sure to charge and discharge it at least once every two or three months. This keeps the battery active and prevents capacity loss due to self-discharge.
4. Safety first
Watch out for any warning signs that your power bank might be failing. If you notice swelling, overheating, strange smells, or unusual noises, stop using it immediately.
Continuing to use a damaged power bank can be dangerous. Also, buy your power bank from reputable brands and retailers like Samsung, Xiaomi or Oraimo.
Counterfeit or cheap knock-offs often lack essential safety features, and reports of power banks overheating or catching fire have increased in recent years due to these unsafe products.
With ongoing advancements in battery technology, power banks are becoming more efficient, compact, and safer.
Features like faster charging, wireless capability, and solar power integration are making portable chargers even more versatile.
Take your time to use and maintain your power bank properly, and ensure that it will be ready whenever you need it.
