I live in a small flat in the city, in the Summer the bedroom gets really hot but I can't open the window because the constant traffic noise will keep me awake. I've tried using a full sized fan but that is too loud for me and it also disturbs my partner. I thought a mini fan might be what I needed and chose this one as it has a few extra features over a standard mini fan.
This mini fan comes with 2 x 2500mAh rechargeable batteries which can recharged from a phone/tablet charger or even a power bank and when charging or charged the fan can even be used as a charger to charge my phone from the USB port in it's stand. Talking about the stand, the stand can also separate and clip onto cupboard doors, headboards, chair arms etc and the fan head can be swivelled to point it in any direction you like.There's also a sponge pad you can fit to the fan that you can use essential oils with so that you can relax and go to sleep whilst smelling your favourite aromas.
This mini fan is operated by a single large rotating knob on the front of the stand which switches the fan off and on and increases or decreases the fan speed to your requirements. I'm happy to say that this fan is quite quiet when it's working and I'm sure won't disturb me or my partner's sleep. Although it's quiet the fan still manages to blow out enough cool air to make the bedroom comfortable to sleep in.
I'm very happy with this Ausein clip on mini portable USB desk fan and to see this on Amazon use this link:-
