But in the market, you’re spoilt for choice, and picking out just the perfect unit for your device can prove harder than you’d expect. Choosing the incorrect one can also mean trouble for your device and wasted money.

If you’re in a power-bank-purchasing dilemma, our guide discusses how to choose the right power bank for your devices. We got product recommendations with the best power bank charger price in Bangladesh, tips, and more, so you land the desired power bank match for your device. 

The Perils of Choosing the Wrong Power Banks for Your Device

You may think you could buy just any power bank and expect it to properly charge your device, but that isn’t the case. You see, power banks have different capacities, and branded units have the specifications outlined. While non-branded, “too good to be true” priced banks promise more than they can handle, like a 20,000 mAh, when in reality, it is only providing 60-70% of its charge.

Over time usage with these mobile accessories in Bangladesh can significantly deteriorate your devices through slow charging, inadequate power, and inconsistent outputs. On the other hand, choosing a lower capacity power bank to charge a higher mAh requiring device can also cause issues. Cheap batteries are prone to overheating and may lead to dangerous electrical fires, while substandard ones may cause short-circuit, risking you and your household to more dangers. 

Choosing the right power bank that can support your device providing effective charging within its capacities saves a whole lot of trouble for you, for your device, and protects your peace of mind. 

How To Choose The Right Power Bank for Your Device

We know you really want to know just the right type of power bank for your devices. So, without further ado, here’s how you can choose the perfect power bank match for your appliance. 

1. Check Your Device’s Battery Capacity (mAh)

When in the market for a power bank, know your device’s battery capacity (mAh), but don’t match 1:1, meaning, don’t choose a power bank with the exact same capacity. The exact pairing won’t result in full charges due to conversion losses, so choose one with 1.5-2x your device’s battery size. A 5000 mAh battery size needs a 7,500 to 10,000 mAh power bank for full charge. 

2. Pay Attention to Output Power, Not Just Capacity

High-capacity is useless if the power bank cannot deliver wattage. Fast-charging phones typically require 18-30W, while laptops and tablets may need over 45W. Please check your device's wattage.

3. Match Charging Standards with Your Device

Devices charge faster only when the right protocol is supported; you want to look for USB-C power delivery, quick charge, or PPS, depending on your phone or tablet.  

4. Choose The Right Port Type and Number of Ports

USB-C is now essential for modern devices and faster charging. If you’re charging multiple devices, make sure the total output does not drop significantly when the ports are shared. 

5. Consider The Size and How You’ll Use It

Larger capacities mean heavier power banks, which may not suit everyday carry. A compact and portable 10,000 mAh is best suited for everyday use and travel. 

6. Check Real-World Efficiency and Safety Features

Quality power banks lose less energy during charging and stay cooler. Safety features such as overcharging and temperature protection are critical for long-term device health. 

7. Factor In Recharge Speed of the Power Bank Itself

Some high-capacity power banks take many hours to recharge fully. Models with fast USB-C input greatly reduce downtime between uses. 

8. Higher Price Doesn’t Always Better Product

A power bank with a high price tag might make you think it’s the right one for your device. But you could be proven wrong when your device is not being charged as you’d expect, and end up deteriorated over time. There are powerful, effective, and affordable power banks on the market that don’t break your bank or your device’s lifespan when you use it. 

These pointers, if you follow them properly, can determine your power bank buying decision to be realistic, well worth your money, and the right one for your device and convenience.

How to Maintain and Store A Power Bank Properly

To prolong the life of your investment, you need to maintain and store a power bank the right way. Sometimes improper maintenance and storage can significantly reduce the effectiveness of your power bank. 

• Avoid Extreme Heat and Cold: High temperature can degrade battery cells, while cold conditions reduce performance and charging efficiency.

• Keep The Charge Level Between 20% and 80% When Storing: Storing a power bank fully charged or fully drained over time can shorten its lifespan.

• Use The Correct Cable and Charger: Low-quality and incompatible cables can cause overheating and reduce charging efficiency over time. 

• Recharge Periodically If Unused: If your power bank is left unused for an extended period of time, recharge the power bank every 2-3 months to maintain battery health.

• Handle With Care and Avoid Physical Damage: Drops or pressure can cause physical damage to internal cells, increasing the risk of performance or safety issues.
