If, like me, you're having to use public transport this week, a personal fan will make your life a lot more comfortable — and I've found just the Amazon Prime Day deal for you. Right now, the Shark ChillPill Travel Bundle is just £119.99 (was £149.99) at Amazon. That includes not just the fan and its three cooling attachments, but a travel case to keep everything safe, and a cross-body strap so you can wear it and stay comfortable hands-free.• See all Prime Day deals at AmazonAfter testing this little fan myself, I loved it so much that I bought my own, and I've not regretted it for a second. My personal favourite is the misting attachment, which sprays you with a fine cloud of vapour when you fill it from your water bottle, but the regular fan and icy cooling plate are a joy as well. Whether you're on a bus or a train, your fellow commuters will be green (and sweaty) with envy.This pocket-sized fan will keep you cool and comfortable anywhere this week, and this bundle with a carry case and cross-body strap is now cheaper than buying the fan by itself thanks to this great Prime Day deal.View DealConsidering how high the temperatures are going to soar later this week, I wouldn't be at all surprised if this deal sells out, so I'd strongly advise grabbing it now if you're tempted. This deal only applies to the silver version, but personally I think that's one of the nicest colours anyway.If you happen to be viewing this article from the US (hello!) then there's good news for you as well if you're feeling the heat — you can grab the Shark ChillPill for $99.99 (was $129.99) at Amazon for Prime Day. This deal doesn't include the carry case and strap, but it's excellent nonetheless, knocking $30 off the list price.Shark's three-in-one fan has received its first ever price cut for Prime Day, and it's a big one, knocking $30 off. It earned a solid 4.5 stars in our review, and will keep you cool and comfortable at home, in the office, or on the move.View DealI'm not expecting the ChillPill's main rival, the Dyson HushJet Mini Cool Fan, to receive any Prime Day discounts, so this is likely to be the best offer we see on a personal cooling system this week.More Prime Day deals in the US Amazon Devices: Fire Sticks & Echo from $18Amazon Haul: viral gadgets, tech & appliances from $1.99Apple: MacBooks, AirPods & AirTags from $29Beauty: 50% off toothbrushes & hair toolsCheap TVs: smart TVs from $69.99Garden: tools, mowers, planters from $24.99Headphones: 50% off Beats, Bose & SamsungLaptops: Apple, HP & Dell from $199Mattresses: Sealy, Serta & more from $186Patio: outdoor furniture, rugs & decor from $19.99Sports: 50% off fitness gear, treadmills & clothingVacuums: Dyson, Shark & Bissell from $34More Prime Day deals in the UK Amazon Prime: sign up for a 30-day free trialAmazon Devices: Fire TV, Ring & Blink from £24.99Amazon Haul: up to 30% offApple: AirPods Pro 3 for a record-low priceAppliances: up to 45% off Ninja, Tefal & SageBeauty: up to 60% off Philips & Oral-BEssentials: household goods from under £10Fashion: up to 50% offFather's Day: up to 50% off gifts & drinksHeadphones: up to 50% offLaptops: from £149.99Tablets: Samsung & Lenovo from £125Toys: up to 25% off Lego and ToniesTVs: from £129.99Vacuums: up to 40% off Eufy & RoborockWearables: Garmin & Huawei from £36.99
