Regarding the purchase of electric hot water bottle, you may use Google to search, but there is no useful information to help you learn further, because there are too many results about B2C for who wants to buy one or two, and we know that you want to make bulk wholesale purchases directly from Chinese original manufacturers, and even want to promote your brand in the target market through OEM.
Another possibility is through Alibaba.com or other similar online B2B marketplaces, but you will still be confused about which product is good and which factory is suitable for your target market needs. Choosing a good manufacturer may cost you too much time.
Therefore, our manufacturer Niubilite will list 5 useful points, so that you can quickly judge the quality of the electric hot water bottle.
Point 1: the stainless steel U shape heating unit
In fact, the heating unit is the most important part of the electric hot water bottle. It determines the charging time, how to heat the water and so on. At present, in the Chinese market, all electric hot water bottle should be divided into two types, namely two types of heating devices. One is the electrode heating unit, and the other is this stainless steel U shaped heating unit.
The electrode type electric hot water bottle is the first batch of products invented in China in 2006. The working principle is to use two nickel-plated iron parts to heat the water in certain salinity water when charging, and when the thermostat automatically cuts off the power, the water will become hotter, up to 75 degrees Celsius.
However, there is a drawback for the heating unit of this electrode working principle. During charging, salt water will corrode the two nickel-iron coated parts day after day. The entire etching process is very slow. After six months, we tested that the rest of the iron component is only half of the original components. Even the original transparent salt water became very yellow and dirty. For such conditions, several Chinese factories only provide six warranty periods, and other manufacturers do not even provide any warranty periods. At the time, we also had six warranty periods until the stainless steel U shaped heating unit for electric water bottle came out.
As usual, because of this electrode type electric hot water bottle in the Chinese market has been used for a long time, almost all know that most consumers use it in the winter as the “famous” old habits. Some countries have imported a few years and think it is normal. If you find that domestic consumers are looking for newly generated electric hot water bottle, we think you should seize this business opportunity. Nowadays, people have ability to afford the quality product which means more profit for you. And there is a marketing case for your reference which is through Google niche, you can find more tutorials to teach you how to start.
Therefore, based on years of experience, in order to continuously improve product quality, the second generation electric hot water bottle began to use this stainless steel U shaped heating unit, which was invented in 2011. From 2011 to 2016, it was a new product and developing rapidly. This electrode is very popular in the Chinese market, most people still buy electrode type electric hot water bottle. But from 2017, more and more consumers began to buy U shaped stainless steel heating unit electric hot water bottle, because it is safer, longer use time, longer warranty period.
The working principle of the stainless steel U shaped heating unit is very simple, because there are electric heating wires inside the stainless steel U shaped heating unit. During charging, the heating unit starts to heat water. When the water temperature reaches 75 degrees Celsius, the thermostat will cut off the power.
Therefore, when you decide to buy this new electric hot water bottle in bulk from a Chinese factory, you should ask the manufacturer to send two samples. A sample is opened to check whether it is inside the product. The other sample should be tested using multiple passes through charging. Using this stainless steel heating device, drinking water can be obtained from the National Water Supply Company. After using this new type of electric hot water bottle one year, the water inside is still as pure and transparent as the original. The warranty period is one year. Consumers can use it for many years, and even change their own water every year. After-sales service is simple and easy.
Point 2: built-in thermostat and fuse
When the water temperature reaches 75 degrees Celsius, the thermostat will detect and automatically cut off the power. The charging lamp will be dark from the lightness. According to our laboratory research, when the water temperature reaches 75 degrees Celsius, the surface temperature of the product is 55-60 degrees Celsius. That is the most suitable for body.
The fuse is mainly used to detect the magnitude of the current to prevent the current from damaging the heating unit. Like other fuses in life, it can only work once.
When you obtain samples (at least 2) from a Chinese manufacturer, you should use knives or scissors to cut one to view these two parts inside the product. Then, you will learn more about electric hot water bottle.
Point 3: anti-explosion charger
It is a complete new charger that can replace the old black charging cable. This is also a very important part. Be careful, you will find that the name contains “anti-explosion”. In addition to charging, like the thermostat, when the water temperature reaches 75 degrees Celsius, it will automatically cut off the power. Then you will doubt how the explosion-proof charger works.
As usual, the product size (27 * 18.5cm) is determined. The amount of water, the voltage and power and the charging time are fixed. When charging, the product must be placed on a flat floor. Once the water temperature is close to standard, the height of the product can be determined, and then the explosion-proof charger will detect the height to automatically cut off the power.
It works almost at the same time as the thermostat works called double protection. In many Chinese manufacturers’ industries, this is just for consumer safety. Electrode hot water bottle does not have this function.
Point 4: Material
The material consists of two parts. One part is the two layers of PVC inside the product to seal the water. Flannel is part of it, and you can feel smooth, warm and soft when you touch it.
For electric hot water bottle, to use your brand for OEM, we will find a flannel color similar to your brand color, and embroider a logo on it, then print the logo on the plastic slide covering the charging socket. Similarly, user manuals and color boxes also use your artwork to showcase your brand. For many factories, choosing a type of fabric is easy, but you should choose the best color to match your logo inspiration.
Point 5: Certification
As we known, CE-LVD and CE-EMC are acceptable in most countries. According to your target market, if the market needs RoHS1.0 or RoHS2.0 or MSDS or AZO certificate to meet some specific needs, you should put forward more requirements on the factory side. For example, we Niubilite have the above, welcome to us.
In conclusion, follow the 5 points to select the best factory you want to cooperate with. You should negotiate with the factory to confirm more order details to balance an optimal price for a long time in the future.
