Features
- Safety & Intelligent Temperature Control This UL-certified immersion heater features a 304 stainless steel cover to prevent direct contact with heating elements and resist rust. The intelligent system automatically shuts off when water reaches 75C (165F), with dual safety protocols: always submerge the heater fully in water before plugging into a 110V outlet, and never expose it to air during operation to avoid fire risks.
- Rapid 2000W Heating for Large Volumes Powered by a 2000W high-efficiency design, this heater warms up 5 gallons (19L) of water in minutes. The perforated guard accelerates heat dispersion while ensuring full submersion. For heavy-duty needs, use multiple heaters simultaneously (on separate sockets) but limit single sessions to 1 hour for safety.
- Portable & Multi-Scene Compatibility Compact and lightweight, it works with buckets, sinks, portable bathtubs, and mini pools (not for large pools). Ideal for travel or outdoor use. Critical warning: Keep at least 3 feet away from flammable materials or gas cylinders during operation.
- User-Friendly LCD Monitoring The built-in digital thermometer displays real-time water temperature, while a power indicator light confirms operational status. Simply immerse, plug in, and monitorbut ensure no humans/pets are in the water during heating.
- Complete Kit with Reliable Service Includes the heater, LCD thermometer, and manualperfect for gifting. Contact AMZKEIO for prompt replacements or troubleshooting with quality guarantees.

I should probably be concerned at how hot I like my bath water. That being said I LOVE LOVE LOVE this product. I can just drop it into the water and not have to worry about draining the water as it cools and adding fresh hot water. From someone who essentially wants to boil while they read a book in the bath this heater is an amazing find. It does feel strange to drop something plugged into an outlet in your bath water, but once you get past that you won't regret it

I’ve been using this portable water heater to warm up water in a small inflatable pool, and it's been almost a month I haven't had any issues. It works well so far. It heats the water a lot faster than I thought it would, and the digital thermometer is super handy for me keeping an eye on the temperature. Setup was simple, I just plug it in and it starts to work. The heat pipes seem solid and it feels well-built overall. I’ve also tried it in a big bucket, and it worked great there too. As long as I follow the safety steps, it does exactly what it’s supposed to do. Definitely useful if you need a quick tool to heat water.

I've been using this portable water heater for about a week to warm water for my inflatable kiddie pool, and it's been surprisingly effective. The unit itself is compact - about the length of a ruler - with a sturdy stainless steel body that feels durable. I appreciate the digital thermometer that clips to the bucket rim; it lets me monitor the temperature without touching the heater. The magnesium oxide heating elements work fast - I measured a 20°F rise in a 5-gallon bucket within 15 minutes.I found the automatic shut-off feature being extra helpful when I got distracted during use - it powered down safely at the max temperature. The included suction cups keep it stable against the bucket wall, though I wish they were slightly stronger. While the instructions emphasize safety (and rightly so - never operate it dry!), the process becomes intuitive after a couple uses. For small-scale water heating needs - from foot soaks to pet baths - this delivers quick, controlled warmth without the bulk of traditional heaters.

This is a portable hot water heater that really surprises me with its efficiency and power. It heats water incredibly quickly. I fill a 6-gallon bucket with water and use it to heat it - within 20 minutes, the water is hot enough for a comfortable shower. It doesn't just warm water - it gets hot, so I often unplug it a few minutes early depending on the situation. Whether it's making tea, washing dishes, or soaking my feet, it can meet my needs. It's also very portable and lightweight. I put it in my camping gear bag and it takes up almost no space. The design is simple and intuitive - plug it in, submerge the coil in water, and it heats up in no time. So far, it's working well!!!

This is a really useful portable water heater that we used on our road trips, but it has become one of my most used gadgets at home! We needed a small and efficient water heater for making tea or bathing my dog outdoors on the road - and this water heater exceeded my expectations in every way. The water heater is small and lightweight, but surprisingly powerful. I simply place the water heater coil in a cup or small pot, plug it in, and the water is steaming hot in minutes. It's intuitive to use, heats up quickly, and its small size makes it ideal for travel. It doesn't take up much space in your bag, and it has a convenient handle and a long enough power cord to easily connect to an outlet.

The media could not be loaded. I needed something to heat water quickly for my stock tanks and this 2000W heater looked appealing. Right from the beginning, the sturdy stainless steel build appears tough – no rust issues to deal with like my old one. The safety features are a huge plus in my books. It heats up so quickly. Seriously, a 5-gallon pail from cold to warm in minutes, exactly as it says. I use it in buckets and my small little portable trough. Most importantly, you MUST respect the warnings. I always go out of my way to make absolutely, positively sure it's completely submerged before plugging it into my 110V outlet, and I keep it way, way away from anything that will burn. It heats up! The guard does appear to dissipate heat very well while keeping it submerged. It's light and easy to drive around my barn or pull out to the field. For the price and the speed, with the safety certifications and wide visibility, it's been every penny worth for my needs. Just be gentle with it – it's a monster.

This portable water heater has been a great solution for warming up my small pool. It’s high power, and really heats the water fast, way quicker than I expected. The stainless steel shell feels solid and durable, and the digital thermometer makes it easy to keep an eye on the temperature. It works exactly as I hoped, and now I can enjoy relaxing in a warm pool without needing to invest in a whole new hot tub. Definitely a budget friendly option that does the job well!

I bought this set of two portable water heaters for business trips and camping, and the price for two felt like a good deal. They’re compact and easy to carry in my bag or car. Once connected to the water hose and power, the water heats up quickly and reaches a stable temperature. It’s perfect for making tea or simple cleaning tasks. The build feels solid, with well-made plastic parts and no strange smell. I alternate between the two units, so having a backup is reassuring. Overall, the value is great—especially for situations where a high-power heater isn’t convenient. It’s ideal for travel during spring, summer, and fall. I’d recommend it to anyone who travels or spends time outdoors often.
