Power Bank Price in Bangladesh by Capacity

Power bank price in BD depends mainly on capacity, charging speed and brand. Here is a simple guide.

Real charges depend on your phone battery and charging efficiency. Bigger power banks are heavier but last much longer.

Our Power Bank Models Explained

Havit PB90 and PB80 (10000mAh)

These compact power banks fit easily in a pocket or small bag. They give one full day of backup for most phones. Great for students and daily commuters.

Havit PB5215 (10000mAh with Display)

The PB5215 shows the exact battery level on a digital display. USB-C support makes charging faster and more modern.

Honor Choice 12000mAh and 20000mAh

Honor Choice power banks offer clean, modern designs. The 12000mAh model is slim for daily carry. The 20000mAh model suits travel and heavy users.

Havit PB92 and TP-Link TL-PB20000 (20000mAh)

These 20000mAh models charge most phones four to five times. They are ideal for weekend trips and long workdays.

Havit PB56 (40000mAh)

The PB56 is our biggest power bank. It can charge phones many times over and keep several gadgets alive during long load-shedding.

mAh vs. Wh: What Do They Mean?

mAh shows battery capacity at the battery's internal voltage. Wh (watt-hours) shows total energy and is used by airlines.

Some energy is lost as heat during charging. So a 10000mAh power bank does not deliver a full 10000mAh to your phone. Around 60 to 70% is normal.

How to Choose the Right Capacity

Choose capacity based on how you use your devices.

• 10000mAh: one day of backup, light and pocket-friendly
• 20000mAh: weekend trips and heavy phone users
• 40000mAh: long travel, families and frequent load-shedding

If you carry a tablet or charge several devices, choose 20000mAh or more.

Key Features to Check Before You Buy

Fast Charging Support

Look for USB-C Power Delivery (PD) and Quick Charge (QC). These charge phones much faster than standard 10W output.

Input and Output Ports

USB-C input charges the power bank faster. Multiple outputs let you charge two or three devices together.

Digital Display

A digital display shows exact battery percentage. You always know when to recharge, like with the Havit PB5215.

Battery Type and Safety

Li-Polymer batteries are slim and safe. Good power banks include overcharge, overheat and short-circuit protection.

Size and Weight

Higher capacity means more weight. Choose a size you will actually carry every day.

Best Power Bank for Every User

Power Bank vs. Portable Power Station

Power banks charge phones, earbuds and tablets. They are small and pocket-friendly.

Portable power stations are much bigger. They can run lights, fans, routers and laptops during long outages. Explore our portable power stations for home backup.

• Power bank: phones, tablets and small gadgets
• Power station: routers, fans, laptops and lights
• Choose both for complete load-shedding backup

Charge Your Power Bank Faster

A power bank needs a good charger too. A USB-C PD charger refills large power banks much faster.

Browse our fast chargers and adapters for quick recharging.

Planning Backup Power for Load-Shedding

Load-shedding can last one to several hours in many areas. A simple plan keeps your family connected.

Step 1: List Your Devices

Write down phones, earbuds, tablets and other gadgets that need charging. Count how many people share them.

Step 2: Pick the Right Capacity

One person with one phone needs 10000mAh. A family sharing devices needs 20000mAh or 40000mAh.

Step 3: Keep It Charged

Recharge the power bank whenever power returns. Make this a daily habit during the summer season.

• Charge phones fully before expected outages
• Use battery saver mode during long cuts
• Keep one power bank at home and one in your bag

Power Banks for Travel and Tours

Long journeys to Cox's Bazar, Sylhet or Sundarbans often mean no charging points. Maps, photos and calls drain batteries fast.

A 20000mAh power bank covers a full weekend trip for most people. Carry a short cable and keep the power bank in your hand luggage.

Group tours benefit from multi-port power banks. Several friends can charge phones at once on the bus or launch.

Power Bank Safety Tips

• Do not leave power banks in hot cars or direct sun
• Avoid charging under pillows or blankets
• Use good-quality cables
• Stop using a swollen or damaged power bank

Airlines allow power banks only in cabin baggage. Most allow up to 100Wh, which covers 20000mAh models.

Power Bank Care Tips

• Recharge before it reaches zero
• Store at around 50% charge if unused for long
• Keep ports clean and dry
• Charge it every few months even if unused

Good care keeps your power bank healthy for years.

Common Power Bank Problems and Quick Fixes

• Not charging the phone: try another cable and port
• Charging very slowly: use a fast charger and PD cable
• Power bank getting hot: stop charging and let it cool
• Lights blinking: the power bank may need a full recharge

Fake power banks often claim huge capacity but weigh very little. They may contain sand or low-quality cells. Always buy genuine brands from trusted sellers.

Charging a laptop? Only USB-C PD power banks with high output can help. Check your laptop supports USB-C charging first.
