What is a good charger should look like ?

ST Chargers — the first professional e-bike charger supplier in China, aims at offer the best quality e-bike chargers for the global brands, launched their new products in 2018.
As we know, even in the Europe with rigorous regulations, some fire accidents happened frequently during the charging for an e-bike battery every year, more and more people realize that a good charger is extremely important. However there are still some e-bike companies in haggle over every ounce at a charger which is vital but the cost of below 1% of the vehicle. What is the difference between $ 12 and $ 22 of the charger ?  What a good charger should be ? Let’s think about it.

Delicate housing

Look at the lap top charger, power bank, speaker, then the e-bike chargers, what is the difference? Yes, the appearance firstly. Why can't the charger be more artistic, more beautiful and more interesting? Well, most the manufacturers have no the consciousness, what they think is how make it cheaper and cheaper. On the contrary, ST chargers asked some professional design companies to work on the chargers housings, and think about how to make a beautiful packaging like the cellphone for the high-end e-bike brands. 
A good surface treatment and appearance charger like an art, make your life more beautiful.

Advanced scheme

An advanced scheme will help to increase the efficiency and make the charger more reliable . It's easier said than done, an advanced solutions need a team for many years of technical precipitation. For example, a 36V2A e-bike charger in the market, normally most of their charging solution is old technology more than a decade ago, low efficiency around 87%, high temperature up to 78 ℃, high repaired rate, etc. After 2 years of concentrated research and development, ST chargers launched their revolutionary new products. 

Smallest dimension

A small charger make your life more convenient.
Thanks for the great improvement of their technology, the dimension of the ST chargers reduced 40%, the weight reduced above 30%. For example, the new ST 36V2A charger is a little big than a mouse, that is mean you can put it into your coat pocket easily and go anywhere. What’s more important, this can help the e-bike manufacturers to reduce the transportation costs greatly. 

Excellent materials

Unlike the other manufacturers who focus on how to reduce the cost through replacing cheaper components, ST chargers always focus on how to use new technology to improve the quality of the products, and keep the price at a reasonable level at the same time. You get what you pay, this sentence is still in charge. For the key components such as capacitors, transformers, relays etc, we choose the most famous and best quality suppliers rather than only think about how to reduce the price.
