Smart Rechargeable Air Cooler Fan

We’re Koyer (Ningbo Keyi Electric Appliance Co., Ltd.) – a 30-year Smart Rechargeable Air Cooler Fan manufacturer rooted in Ningbo, and we’re proud to say the waterproof performance of our 55L solar-powered dual-mode air cooler has won rave reviews from outdoor enthusiasts!

One of our customers shared: "A sudden downpour hit my balcony, and the unit got soaked for 20 minutes. After wiping it dry, it turned on and cooled perfectly – no issues at all!" That’s all thanks to its IPX7 waterproof rating, which we engineered to handle splashing rain on balconies, dampness from courtyard watering, and all kinds of semi-outdoor scenarios.

We designed it so you can place it on the balcony during the day to charge via sunlight, enjoy 4-14 hours of continuous cooling on a full charge, and the 55L large water tank means you won’t have to refill it constantly. Plus, switching between AC and DC modes is a breeze – we made sure it’s reliable, energy-efficient, and hassle-free for both home and semi-outdoor use!

Product Parameter

Product Application

Our 2025F portable air cooler is tailor-made for outdoor use—unlike ordinary air coolers on the market, it truly addresses the core pain points of outdoor applications, blending rugged practicality with reliable performance to deliver a superior experience for your outdoor adventures, work sites, and casual gatherings. Most outdoor air coolers use regular plastic materials with poor wear and weather resistance, but our unit is crafted from high-quality ABS + PP plastic that easily withstands outdoor impacts, sun, and rain.

What’s more, it boasts the customer-loved IPX7 waterproof rating—while many competitors only offer IPX4 protection, which makes them vulnerable to sudden downpours or courtyard watering, the 2025F can operate safely even when directly exposed to water, so you never have to worry about unexpected weather.

When it comes to portability, similar products often sacrifice flexibility for large capacity: either they’re bulky (most over 600*400*1100mm) or weigh over 15kg, making them a hassle to carry. In contrast, the 2025F maintains a 55L extra-large water tank while keeping its dimensions at 505*350*1050mm and net weight at just 11.0kg—no extra help needed to move it easily to your patio, campsite, or work site.

Customization

We also offer flexible customization services to meet your specific needs: from user manuals and nameplates tailored to your brand standards, to custom branding (logo printing/embossing), color matching for the casing, personalized packaging designs (including outer cartons and inner buffers), and region-specific plug adapters (EU/US/UK/AU standards, etc.). Whether you’re building your own brand or fulfilling bulk orders for specific markets, we can adjust every detail to align with your requirements—making the 2025F truly your exclusive outdoor cooling solution.
