Laptop-capable 100W models like the Baseus 20000mAh and Shargeek Storm 2 reach ৳6,900–৳20,490. Brands include Anker, Baseus, Xiaomi, Joyroom, Remax, QCY, Awei, Hoco, UGREEN, WIWU, FONENG, Momax and Rocoren.

Capacity: What the Number on the Box Really Means

Rated capacity is not delivered charge. A power bank stores energy at 3.7V and charges your phone at 5V, and that conversion costs about 30–35%. A 10,000mAh power bank therefore hands over roughly 6,500mAh — around one and a half charges for a 4,500mAh phone, not two.

1. 5,000mAh (from ৳1,990) — one partial charge. Thin enough to sit under a phone as a magnetic pack.
2. 10,000mAh (৳1,050–৳2,100) — one and a half charges. Pocket-sized, and what most buyers pick.
3. 20,000mAh (৳1,790–৳3,300) — three to four charges, or a phone plus earbuds and a watch.
4. 30,000mAh and above (৳2,450–৳4,850) — multi-day trips. Note the airline limit: 100Wh, about 27,000mAh, so a 30,000mAh unit may be refused at security.

Wattage Decides Speed, Not Capacity

A 60,000mAh power bank with 22.5W output charges a phone no faster than a 10,000mAh one with the same 22.5W. Capacity decides how many times; wattage decides how quickly.

1. 15W–18W — basic. Fine overnight, slow in a hurry.
2. 20W–22.5W — about 50% in half an hour on most phones. The sweet spot for price and speed.
3. 30W–45W — tablets and fast-charging flagships.
4. 65W–100W — laptops. The Joyroom JR-PBF05 65W and Baseus 100W will run a notebook; nothing below 45W will.

Your device sets the ceiling. A phone that accepts 18W draws 18W from a 100W power bank, so paying for headroom you cannot use is wasted money.

What to Check Before Buying

1. Pass-through charging — charges your phone while the power bank is itself plugged in. Genuinely useful during load-shedding.
2. Digital display — an exact percentage instead of four vague LEDs. Common on Baseus and Joyroom models here.
3. Built-in cable — one less thing to forget, but it is the first part to fail. Prefer models that also have a free USB-C port.
4. Weight — a 20,000mAh unit weighs around 400g. That is noticeable in a shirt pocket, unremarkable in a bag.

For iPhone 12 and later, see magnetic wireless power banks, which attach to the back of the phone without a cable.
