Jisulife makes the best portable fan we’ve tested. Several models are now up to 45% off

After testing eight portable fans, our editor found Jisulife to offer the all-around best way to beat the heat while away from home. With summer in full swing and heat waves popping up across the country, there hasn’t been a better time to supplement your air conditioner or tower cooling fan with a personal cooling device, especially now that several of Jisulife’s fans are marked down to their best prices of the year at Amazon.

Throughout the sale, you’ll be able to save on several different devices, across several price points, to make the season’s high temperatures a bit more bearable. I’ve found deals that start at just $12, taking as much as 45% off normal price tags.

Jisulife Life7 3,600mAh Handheld Fan

If you're looking to skip right to the best value from this week's Jisulife sale, look no further than this Life7 handheld fan and its 40% discount. This is a new Amazon low price on a compact cooling fan that is $5 below its previous Amazon Prime Day offer and comes in two colors. Its 3,600mAh battery can run for up to 13 hours on a single charge, depending on which of the five speed settings you choose, and I appreciate the fan's added LCD display, which shows the remaining battery levels throughout the day.

Jisulife Life9 Portable Handheld Fan

Jisulife's Life9 fan isn't as cheap as the Life7, but what it lacks in an affordable price tag it makes up for in the features department. This portable fan packs a larger 5,000mAh battery — and can cool you down for up to 18 hours in a row — into a more compact design than its more affordable counterpart. Several colors are on sale for its second-best price to date, which lands within $2 of the lowest price set on Black Friday.

Jisulife Portable Neck Fan

Do you prefer a wearable neck fan over one you have to hold in your hand? This Jisulife model looks like a pair of over-ear headphones that rest around your neck to offer a more discreet cooling solution this summer. It's up to 20% off in the green option, with additional colors also on sale for varying prices.

Jisulife 4,500mAh Mini Portable Bladeless Fan in White

The smallest portable fan on this list also happens to be paired with the largest discount. Amazon is taking 45% off for those who want a compact option that fits in pretty much any purse, bag or backpack. It packs in a sizable 4,500mAh battery that yields up to 16 hours of usage on a single charge, and it has the same five-speed settings that you'll find from some of the other discounted Jisulife fans.

Jisulife Chic Oscillating Stroller Fan

Alongside its more conventional fans, Jisulife also makes a mountable fan that allows you to attach a cooling breeze to a stroller or set up on a nightstand. Two different models are on sale based on whether you'd prefer a clamp design or one with four adjustable legs. Each one includes an oscillating fan that can be dialed in to the perfect level with 100 speed settings. You'll also be able to choose between two distinct wind modes that mimic a natural breeze or dish out stronger gusts of wind.

Jisulife 3-in-1 Portable Handheld Fan

This handheld fan folds up when you're not using it to stow away in smaller bags and spaces more comfortably than any of the other discounted models on this list. Several colors are on sale, but the best discount applies to the Blue style at $4 off its normal price.

Jisulife Pro1S Handheld Fan

It might be pricey, but those who want one of the most capable portable fans from Jisulife can save on the Pro1S model. This rivals the features you'll find on higher-end alternatives like the Shark ChillPill and Dyson HushJet Mini, thanks to a premium metal build that can dish out wind speeds of more than 9,700 revolutions per minute with its 100 customizable settings.
