Power bank price in Bangladesh: settle capacity before you filter
The power bank price in Bangladesh spans ৳ 1,199 to ৳ 7,990 on this page, and almost none of that spread is brand prestige. It is capacity, charging speed, and whether the unit sticks to your phone.
Forty of the 50 models above are 10,000mAh, nine are 20,000mAh, and exactly one is 30,000mAh. Capacity is the first filter to touch, because it decides most of what you pay and all of what you carry.
Work out how long you need to go without a wall socket, then read the bands below. If the answer is one day, stop at 10,000mAh and spend the difference on watts.
Power bank price in Bangladesh 2026 by band
These four bands come from the actual price spread of the 50 power banks above, not from round numbers. Each row names a model in that band today.
| Band | Price range | What it buys | Example |
|---|---|---|---|
| Entry | ৳ 1,199 – ৳ 1,999 | 10,000mAh, 15W to 22.5W, one USB-A plus one Type-C | Havit PB90 10000mAh 22.5W power bank at ৳ 1,400 |
| Mid | ৳ 2,000 – ৳ 2,499 | Faster 10,000mAh units at 20W to 25W, or your first 20,000mAh | Bwoo BO-P71 20000mAh fast charging power bank at ৳ 2,220 |
| Upper-mid | ৳ 2,500 – ৳ 3,199 | 30W output, dual protocols, magnetic wireless, built-in cables | Joyroom JR-PBC06 30W mini power bank with dual cables at ৳ 2,799 |
| Premium | ৳ 3,200 – ৳ 7,990 | 30,000mAh, 65W laptop charging, branded magnetic units | Riversong Phantom Pro 65W 20000mAh power bank at ৳ 3,999 |
Capacity moves the price less than you would expect: the cheapest 20,000mAh unit is ৳ 2,220, barely above a good 10,000mAh one. And only one 30,000mAh option is in stock, the Hoco Astute 30000mAh 22.5W power bank at ৳ 3,200.
Why a 10,000mAh power bank does not give your phone 10,000mAh
The number on the box measures the cells inside, which run at about 3.7 volts. Your phone charges at 5 volts or higher, so every milliamp-hour is converted upward, and conversion costs energy. Heat and the circuit take another slice.
In practice a 10,000mAh power bank delivers around 6,000 to 6,500mAh. Against a typical 5,000mAh handset battery that is one full charge and most of a second, not the two the label implies.
The honest figure is watt-hours. A 10,000mAh pack is roughly 37Wh and a 20,000mAh pack roughly 74Wh. That number is printed on the underside, it is what airlines check, and it is the only figure that compares two packs fairly.
Fast charging power banks: watts, ports and magnets
Once capacity is fixed, output wattage separates a 20-minute top-up from an hour of waiting. Every model above states its wattage in the title.
15W to 22.5W: the normal choice
Most of the catalogue sits here. It suits any phone that charges at 18W to 25W from the wall, refilling a 5,000mAh battery to about half in half an hour.
Suggested
Hoco J105 22.5W 10000mAh power bank — ৳ 1,979
25W to 30W: for big-battery phones
Worth the premium if your phone shipped with a 30W or faster charger. Below that speed the extra watts sit unused and you have paid for nothing.
Suggested
Joyroom JR-PBF20 25W 10000mAh power bank — ৳ 2,100
PD or QC: match your phone
Power Delivery runs over USB-C and charges iPhones and most recent Android flagships. Quick Charge runs over USB-A and suits older Snapdragon phones. A dual-protocol pack removes the guesswork.
Suggested
USAMS 20000mAh PD20W and QC3.0 dual-port power bank — ৳ 2,500
65W: enough for a laptop
Anything at 45W or above over USB-C charges most ultrabooks, and pairs sensibly with a laptop bought in Bangladesh. It is the only real reason to spend past ৳ 3,500.
Suggested
Riversong Phantom Pro PB103 65W power bank — ৳ 3,999
Magnetic and wireless
Fourteen models here charge magnetically or wirelessly. They are slower than a cable and they only clamp properly to an iPhone 12 or later, or an Android phone in a MagSafe-compatible case.
Suggested
Ports and built-in cables
Two outputs let you charge a phone and earbuds together, though the wattage splits between them. Built-in cables save you carrying one, but they wear out first — keep a spare from data cables in Bangladesh.
Suggested
Anker Zolo 10000mAh power bank with built-in Type-C cable — ৳ 3,470

Five mistakes that waste money on a power bank
Chasing mAh instead of watts
A 20,000mAh pack at 10W charges slower than a 10,000mAh pack at 30W. Capacity decides how many refills you get; wattage decides how long each one takes.
Missing a counterfeit
A genuine 20,000mAh unit weighs roughly 350 to 450 grams. If it feels light, or the price sits far under the ৳ 2,220 that the cheapest real 20,000mAh model costs here, the cells inside are not what the label claims.
Ignoring protection circuits
Over-charge, over-discharge and short-circuit protection are standard on every branded unit above and absent from unbranded market stock. This is the specification that decides whether a fault becomes a fire.
Buying magnetic for the wrong phone
Magnetic packs grip iPhone 12 and later. On most Android handsets they slide off unless you add a metal ring or a compatible case, and then they charge at reduced speed anyway.
Using the cable that came free
A 30W power bank paired with a 2A cable delivers about 10W. Check the cable rating, or pick one up from chargers and charging accessories.
Assuming passthrough works
Passthrough means the pack can charge your phone while itself plugged in. Many units cannot, and doing it anyway on a pack that is not rated for it runs both batteries hot.
Buying a power bank in Bangladesh: load-shedding, warranty and flights
Load-shedding
If outages run two or three hours, a 10,000mAh pack is fine. If they run longer or repeat through the day, go to 20,000mAh with at least two output ports, so charging one phone does not lock out a second. Charge the pack overnight, not during the evening peak.
Warranty and service
Warranty here usually runs six to eighteen months and is honoured by the local distributor, not the manufacturer. Anker and Ugreen have the widest service coverage in Dhaka and Chattogram; smaller brands are handled seller-side. Keep the box and invoice — most claims are refused without them.
Flights, heat and storage
Airlines operating from Dhaka allow power banks up to 100Wh in hand luggage only, which covers everything on this page including the 30,000mAh unit. Never put one in checked baggage. During the monsoon, store the pack somewhere dry and out of a parked car, since sustained heat above 40°C permanently reduces cell capacity. If you leave one unused, top it to about half charge every three months rather than storing it empty.
EMI is available on higher-value orders, which mainly matters in the premium band. It rarely makes sense on a ৳ 2,000 pack. For in-car use, a 12V adapter from mobile car accessories is cheaper than running a power bank down daily.
Power bank questions from Bangladeshi buyers
What is the power bank price in Bangladesh?
Power bank prices in Bangladesh run from ৳ 1,199 to ৳ 7,990 across the 50 models listed on this page. Entry-level 10,000mAh units sit between ৳ 1,199 and ৳ 1,999, 20,000mAh packs start at ৳ 2,220, and the single 30,000mAh model costs ৳ 3,200. Prices move with capacity, output wattage and magnetic charging support.
How many times will a 10,000mAh power bank charge my phone?
A 10,000mAh power bank gives most phones one and a half to two full charges. Voltage conversion and heat consume roughly a third of the rated capacity, so about 6,000 to 6,500mAh actually reaches your device. Against a 5,000mAh phone battery that means one complete charge plus a substantial top-up, not the two charges the label suggests.
Is a 20,000mAh power bank worth the extra money?
A 20,000mAh power bank is worth it if you go two or more days between wall sockets. The cheapest one here costs ৳ 2,220 against ৳ 1,199 for the cheapest 10,000mAh, so the capacity roughly doubles for about a thousand taka. The trade-off is weight, around 400 grams, and a longer recharge time.
Can I take a power bank on a flight from Dhaka?
Yes, power banks must travel in hand luggage and stay under 100 watt-hours. A 20,000mAh pack is about 74Wh and a 30,000mAh pack about 111Wh, so the largest units can be refused at the gate. Checked baggage is never permitted. Carry the pack where cabin crew can see the printed Wh rating if asked.
What is the difference between PD and QC fast charging?
PD is the USB-C standard and QC is Qualcomm's, delivered over USB-A. Power Delivery charges iPhones and most current Android flagships; Quick Charge suits older Snapdragon handsets. Check which charger shipped in your phone's box, or buy a dual-protocol pack such as the USAMS 20000mAh at ৳ 2,500 and stop worrying about it.
Which power bank is best for load-shedding?
A 20,000mAh unit with two or more output ports handles load-shedding best. It covers several hours of outage across two phones without needing a recharge itself. The Bwoo BO-P71 20000mAh at ৳ 2,220 is the cheapest option that meets both conditions. Charge it overnight so it is full before the evening outage window.
Can a power bank charge a laptop?
Yes, if it delivers at least 45W over USB-C Power Delivery. Most ultrabooks charge at 45W to 65W, so a 65W pack such as the Riversong Phantom Pro at ৳ 3,999 will run one. Lower-wattage packs will slow the battery drain but not actually charge the machine while you use it.
Do magnetic power banks work with Android phones?
Magnetic power banks stick to Android phones only with a metal ring or a MagSafe-compatible case. The magnet array is built for iPhone 12 and later. Without one of those accessories the pack will slip off, and even when it holds, wireless charging runs at 15W or less against 22.5W or more over a cable.
How long does a power bank last before it needs replacing?
Most power banks hold usable capacity for about 300 to 500 charge cycles, which works out to roughly two to three years of daily use. You will notice it first as slower recharging and fewer refills per charge. Heat shortens this considerably, so a pack left in a hot car ages faster than one kept indoors.
How can I tell if a power bank is genuine?
Check the printed capacity against the weight and the price. A real 20,000mAh pack weighs 350 to 450 grams and costs at least ৳ 2,220 in Bangladesh. Counterfeits feel light, omit the watt-hour rating, and print no model number you can look up. Buy from a listing that names the brand, the model and the wattage.
Narrow it down
Set the capacity filter first, then sort by price and read the wattage in each title. Two comparisons settle most decisions: Awei P20K at ৳ 1,199 against Havit PB90 at ৳ 1,400 for the cheapest useful pack, and Bwoo BO-P71 at ৳ 2,220 against Adata C20 at ৳ 2,390 for 20,000mAh. If the brand is already decided, open its brand page, or browse the wider mobile accessories range and mobile phones in Bangladesh to match the pack to the handset.
