They say fame is a burden for people just as weight is for pigs — but what do divers fear most? If you've ever suffered a pounding headache or the creeping discomfort of hypothermia from chilly water, you'll know the answer all too well. What should be an exhilarating dive trip can end prematurely with you flat on your back onshore. Unfortunately, Taiwan's subtropical location means that once Mid-Autumn Festival passes, diving in the north is practically called off — water temperatures slide from a summery 28°C straight down to 19°C. Even southern spots like Kenting and Xiaoliuqiu, which benefit from lower latitudes and the warming influence of the Kuroshio Current, can still see temperatures dip below 24°C at certain dive sites.
Cold tolerance varies from person to person, but as a general rule, a 3mm wetsuit is the go-to below 28°C, while anything under 22°C calls for a 5mm wetsuit plus a hood — or even a drysuit — to endure prolonged immersion in frigid water. Thicker suits are not only a hassle to put on and take off; their added bulk increases buoyancy, forcing you to carry extra weights underwater, making the entire dive that much harder.
In recent years, the international dive market has seen a wave of heated electric vests designed specifically for cold-sensitive divers. Yet awkward designs, oversized battery packs, and cumbersome configurations have kept many divers from taking the plunge on a purchase. The POWAT Waterproof Heated Illumination Vest is a Taiwan MIT product — designed, assembled, and tested locally — built around three key design highlights aimed at helping all diving enthusiasts extend their dive season and make every dive more comfortable.

1. POWAT Waterproof Heated Illumination Vest: "Patented Battery Technology"
The POWAT Waterproof Heated Illumination Vest positions the battery outside the wetsuit, allowing flexible placement configurations.
The battery is one of the standout highlights of the POWAT Waterproof Heated Illumination Vest. It is licensed to use Panasonic cells from Japan, guaranteeing both longevity and safety. Charging is handled entirely via wireless charging technology — simply place the battery on the charging dock and it begins charging automatically. This means the battery assembly uses absolutely no O-rings, dramatically reducing the risk of hardware degradation from maintenance and long-term use.
Divers can control heat output through five levels using the button on the battery unit itself. On a full charge, the third heat setting delivers approximately 3 hours of use — enough for roughly 2–3 scuba tank dives. Future design iterations may also incorporate temperature sensing to prevent overheating. Positioning the battery outside the wetsuit offers two key advantages: existing heated vests on the market house their batteries inside the wetsuit, where the hard battery pack can press uncomfortably against the body. Should a malfunction cause excessive discharge and overheating, the diver has no easy way to address it mid-dive. With the POWAT's external battery placement, all it takes to fully isolate an anomaly is releasing the D-ring and disconnecting the wireless charging module — a significant boost in safety.
2. POWAT Waterproof Heated Illumination Vest: "Wireless Power Transfer Technology"
The POWAT Waterproof Heated Illumination Vest integrates the heating module and battery module via wireless charging technology.
The heated vest also leverages wireless charging technology in its day-to-day operation. The battery assembly and heating element are magnetically coupled using powerful magnets, providing wireless power transfer without disconnecting — even with up to 5mm of wetsuit material in between. This design allows you to position the heating panel anywhere on your body and deliver heat through the wireless charging module. The battery itself sits outside the wetsuit and can be clipped onto a D-ring, doubling as a weight (approximately 920 grams). In any emergency — or when swapping out a battery — simply detach the wireless charging module with ease. This is the single biggest differentiator between POWAT and comparable products on the market.
3. POWAT Waterproof Heated Illumination Vest: "Ultra-Thin LED Illumination Module"
The POWAT Waterproof Heated Illumination Vest's underwater light source serves as a highly practical identification aid.
Perhaps the most eye-catching feature revealed at launch is the illumination panel integrated into the chest area. It uses 24 high-brightness LED ultra-thin flat diffusion lights that can serve as a lighting source when entering or exiting the water during night diving. The panel generates no heat of its own and can be left on for extended periods. During low-visibility dives along the Northeast Coast, it can also act as a powerful tool for instructors during training — giving students a clear visual reference to locate their instructor underwater. In the future, instructors and dive shops will be able to choose from different colored filters and graphic cards to create a unique, customized identification system for their own teams.
The POWAT Waterproof Heated Illumination Vest will support interchangeable color filters for team identification.
The arrival of the POWAT Waterproof Heated Illumination Vest aims to extend everyone's dive season. For example, instructors and dive shops along the Northeast Coast who previously couldn't start teaching or leading guided dives until May can, with the POWAT vest, add several extra months of operational time to their season. Providing students with this kind of equipment allows them to comfortably complete every dive, building trust and a sense of professionalism — great service is built one small detail at a time.
Another target user group is underwater photographers who spend long stretches motionless on the seabed, shooting macro subjects. Prolonged exposure to cold water causes physical discomfort and can even impact shooting efficiency. The POWAT Waterproof Heated Illumination Vest is designed to give divers a warmer, more comfortable dive experience.
The POWAT Waterproof Heated Illumination Vest can be quickly detached underwater for troubleshooting.
Beyond water sports enthusiasts, anyone who needs to stay warm outdoors for extended periods in conditions requiring waterproofing can benefit from the POWAT Waterproof Heated Illumination Vest — anglers, high-altitude rigging crews, outdoor construction workers, and even cyclists braving winter commutes can wear it under their regular clothing for warmth. Its range of use cases is as wide as it is versatile.
