Giving fans an insight into her filming experience in Bulgaria, Michelle revealed she's been using this handheld portable fan to battle the summer heat. And we think we've found the one she's been swearing by this summer.

This Amazon Handheld fan looks just like the one Michelle used. It boasts a relatively small space, which makes it ideal for carrying in your hand, around your neck on a lanyard, or storing in your bag while you're on the move. It features a 90-degree foldable design that means it can also be propped on a table or desk to keep you cool while you work or sleep, completely hands-free.

This portable fan retails for a wallet-friendly £16.99 and is available in a wide range of colourways, including Michelle's choice of black shade.

Touted as ultra-quiet, this handheld fan boasts six adjustable speeds. The wind speed can be gradually increased from 1 to 5, depending on how cold you want the air. The sixth speed simulates a natural wind, ensuring you can keep cool with a less intense, gentle breeze.

This handheld fan has a long-lasting battery life and a rechargeable 4000mAh large-capacity battery. It can work continuously for 4-18 hours (depending on the speed setting. Plus, it recharges super fast, only taking 1.5 hours to fully charge. Promising to to suit any busy day, whether you're getting your hair done on set like Michelle, heading to the beach, working in an office or travelling on a train, this fan is set to last all day - and if it's charge does run out, it's convenient to replenish its battery life with a simple portable charger or a quick plug in while you're out and about.

Boasting an impressive 4.6 out of 5-star rating on Amazon, with over 8600 reviews, this fan has amassed plenty of praise from satisfied customers. One thrilled buyer beams: "This fan has been a lifesaver whilst pregnant! I took it on holiday with me, immediately used it in the airport as security was long and no air con before getting through to departures, used it in bar areas, outdoors on the beach, round my neck to carry it, and then on my return I'm able to pop it on desks at work when needed as it folds to accommodate being on sides."

They go on to add: "The charge lasts well on levels 1-3 goes much quicker on the higher functions. I love how easy it is to use and it's definitely portable but powerful! It's pretty quiet depending where you are too and the function where you can use it as a powerbank in a pinch was brilliant. Cannot recommend this fan enough!"

Another happy shopper raves: "Very happy with this fan - I've bought a number of different fans over the years, and while all are good, I realised this one was the best when I was comparing them all in terms of noise, wind speed / impact, and overall design / look / functionality etc. This fan has 6 settings, and is less noisy than the others, but probably the best airflow. What I noticed about this fan is that the airflow goes directly into your face, whereas some other fans can sort of fan the air around the side of your face, but not right into your face - so that was a big plus for this fan."

They continue: "Also, I love the sleek design of this fan as well as the colour. Also a great size and sturdy (while also flexible when moving the handle), and the battery charge life also seems great. It's also great that it tells you the percentage of battery left, as other fans often just have a simple 3 bars - whereas this fan has the exact percentage so easier to know how much you truly have left. Very happy, thanks! Will probably be buying a second one soon!"

And a third chimes in: "This fan is AWESOME. I used it on a recent holiday to Africa and it worked perfectly and was very effective at keeping me very cool (I wish I had bought 2 as my relatives kept borrowing it....the fan was that good). Once fully charged it lasted me the whole day and I would usually leave it to charge overnight. It's a great, sturdy little fan and you should definitely get it."
