Originating in the USA, Diveblues is a leader in turbo fan innovation and high speed cooling, using the latest technology to deliver powerful airflow for those on the move. The brand specialises in performance, portability, and durability, and makes a range of fans that are ideal for the outdoors. Whether at camp, trekking through the mountains or exploring a new town or city, Diveblues handheld fans offer added comfort when the temperatures rise.

The Diveblues JetForce uses a high-performance six-blade design with powerful three-phase brushless motor, which delivers wind speeds of up to 10m/s, and 13,500rpm, three times stronger than a standard handheld fan. The USB rechargeable fan has five adjustable wind settings, delivering up to 12 hours of cooling on a single charge, and is compatible with other devices, such as laptops, power banks and car chargers. The speed level and charge status are shown on an LED display and the JetForce can be used in three ways: Handheld; around the neck (it comes with a neck strap); or sitting on a table or other flat surface. The compact fan has dimensions of 17.02 x 5.59 x 4.57cm and weighs just 190g. It retails at £22.95.

The Diveblues iTurbo is very lightweight at only 132g and measures just 15.24 x 4.83 x 4.32cm. With five settings, it is capable of producing wind speeds of up to 9.2m/s, around three times more powerful than a standard handheld fan, and like the JetForce, it can be used in three ways. An LED display shows the speed level and status of the charge. The single Type-C rechargeable 4000mAh battery will provide power for up to 11.5 hours of cooling. The iTurbo retails at £19.95.

All Diveblues fans are built for extended use while travelling and in a variety of outdoor settings. New to the UK, the JetForce and iTurbo will be available from mid-June at www.berryuseful.co.uk.
