Quick answer

For one person at a desk, in bed or on the move, a handheld fan with a 3,600mAh or bigger battery is the most practical choice. The JISULIFE Pro1 (৳3,790) runs about 2 hours on top speed and up to about 12 hours on low, and recharges from a power bank. For cooling a whole room through long outages, a larger 12–17 inch rechargeable table fan is the better fit.

Load-shedding in summer can mean hours without a ceiling fan. A rechargeable fan fills that gap, but the backup time printed on the box is often the best case, not what you get on a hot night.

This guide explains what really decides backup time, so you can choose the right size of fan.

What decides a fan's backup time

  • Battery capacity: more mAh (or Wh) stores more energy. Compare capacity, not just the hours on the box.
  • Speed setting: this matters most. The JISULIFE Pro1 is rated about 2 hours on maximum but up to about 12 hours on low, a six-times difference from the same battery.
  • Fan size: a bigger blade moves more air but needs more power, so a table fan needs a much larger battery to last as long.
  • Motor type: brushless motors, like the one in the Pro1, generally waste less energy as heat than older brushed motors.
  • Battery age and heat: lithium batteries slowly lose capacity over time and with heavy use, so a fan that ran 10 hours when new will run less after a year or two.

A simple rule: rated hours at low speed are the maximum. On a hot night you will probably run it faster, so plan around the high-speed figure.

Handheld fan or rechargeable table fan?

A handheld fan cools one person. It is light, fits in a bag and works on a bus, rickshaw or in a hot classroom, as well as at home during outages.

A 12–17 inch rechargeable table fan, from brands such as Walton, Singer or Defender, is what most Bangladeshi families buy to cool a bedroom through a long outage. It is bulky and needs wall charging, but it moves far more air.

Many homes keep both: a table fan for the bedroom and a handheld fan for whoever is studying, cooking or travelling.

Stretch backup with a power bank

Because the Pro1 charges over USB, any power bank can top it up during a long outage. A 20,000mAh power bank stores several times the Pro1's 3,600mAh battery, so it can refill the fan more than once even after conversion losses.

Charge the fan and the power bank whenever electricity is back, so both are full before the next outage.

Frequently asked questions

Which rechargeable fan is best for load shedding?

It depends on the space. For a whole room through a long outage, a 12–17 inch rechargeable table fan from Walton, Singer or Defender is the usual choice. For one person at a desk, in bed or travelling, a handheld fan with a 3,600mAh or larger battery, like the JISULIFE Pro1, is lighter and can charge from a power bank.

How many hours does a charger fan last?

It depends on battery size and speed. The JISULIFE Pro1, with a 3,600mAh battery, is rated about 2 hours at top speed and up to about 12 hours on low. Larger table fans list their own backup times, but those figures are usually measured at low speed, so expect less on high.

Can I charge a rechargeable fan with a power bank?

Yes, if the fan charges over USB, as handheld fans like the JISULIFE Pro1 do. A power bank lets you recharge the fan during a long outage. Larger table fans often use their own adapter, so check the charging input on the box before relying on a power bank.

Which charger fan is best in Bangladesh?

Choose by use. Handheld fans with brushless motors and 3,600mAh or bigger batteries suit personal cooling and commuting. Rechargeable table fans suit bedrooms during long outages. Whichever you pick, buy a genuine branded model from a seller with a return policy, because battery quality is hard to judge from photos.
