As the weather heats up, it can be hard to keep cool when you're out and about. Many small fans just don't cut it, or are too tricky to hold or transport.

But the SmartDevil Octopus Fan, $36.99, is a portable fan with over 1,700 5-star reviews, with people claiming it's "powerful," "excellent" and "high quality."

The fan is designed to attach to prams, car seats, or anywhere else you can think of - and is made from bendable metal with a silicone surface. This means you can bend it to any angle you want, using it as a desk fan, wall fan, or just hold it where you need.

It has three speeds, and an ultra fine mesh on the front cover which means it's safe for babies if they put their fingers in it. It uses a brushless motor to provide a strong wind, with low noise, meaning it's ideal for work or when you're sleeping.

It's powered either by battery or USB, and it can be charged through your computer, USB charger or car. It works for up to 10 hours at full charge.

The front cover of the fan is detachable, so the grille can be washed to remove any dirt or dust. It gives complete 360 vertical and horizontal rotations, so you can point the wind in any direction you need, and is light and compact so can easily be carried in a bag.

Fans are buying several so they can keep one in the car, one in their bag, and keep one at home too. "Great value, quiet and powerful," says one happy user. "Excellent," agrees another.

If you're looking for another type of fan to carry around with you this summer, there are plenty of other options.

The SmartDevil Mini Handheld Fan, $29.99, is a spiral, double layer fan. Because it has a double motor, the wind is more concentrated and promotes air circulation. It has three speeds, and can be handheld or carried round your neck with the silicone lanyard. When charged, it lasts up to nine hours.

The Viniper portable neck fan, $18.99, can be hung around your neck, so you're cool while being hands-free. With 360 degree rotation, it has three speeds and a quiet motor. It can also be twisted to sit upright, so you can sit on a table or desk.

The SUMAX Mini USB Handheld Pocket Fan, $21.99, has a high power motor and looks good too - it has three adjustable speeds, and is perfect to keep in your bag for when you need a bit of breeze.
