Many chargers come with the bike brand name but are actually Chinese OEM chargers. A few companies like bosch probably produce their own. And a few like Shimano and Yamaha probably have chinease companies manufacture unique chargers for their system. We get to see a lot of chargers so here is few namnes i picked up.
Shenzhen Fuyuandian Power Co.,Ltd
Also called HF-FYD. Makes charger from 7.4-68V. From what i know very cheap but does not mean low quality. A common model looks like this:
Shenzhen Gojusin Technology Co.,LTD
https://www.gojusin.com.cn/ (Chinease only?)
Tianchang Junnuo Electronic Technology Co., Ltd
Never heard of them and only has 207 google results. BUT JN-60 is a 67.2V charger for city coco with a fan that often brakes which makes this charger crap! Really low quality!
PortaPower (HK) Limited
Very large supplier of OEM batteries and chargers for many consumers products! Makes chargers for ebikes from 60W-1200W (claim). They seldom put their names on the chargers but the 42V 1.35A (ACK4201N) charger is very common in eu since Promovec uses it and it also came with many ebike kits. We dont know if they manufacture them because their other chargers comes from Modiary/MDA, Fuyuandian, Sans Wuxi and Kunchan ST etc. But this early charger might be their own. Their battery cases are mostly from Shan Shan Plastic.
Shenzhen Hyleton Technology Co. ,Ltd
Cant find any current info at all. Might not exist anymore.
Kunshan ST Electronics Co., Ltd
Very popular in EU! Mainly 24-48V chargers 60-270W.
Wuxi DPower Electronics
Not the same as Wuxi Sans. Makes 24V/36V chargers that look a lot like Sans Wuxi /ST Kunchan. But also has 300W fast charger which i believe BionX used back in about 2010 and was also used by some other brands for Nimh/lead batteries. The 600W series are very common as a high power charger on aliexpress sold by WATE and many other. Not sure if its exactly the same but sold as 48V-72V 4A commonly.
Shenzhen Yongletong Electronic Technology Co., Ltd.
No info found and does not seem to be active.
Shenzhen Jueneng Electronic Technology Co.,Ltd
Seems to be a small company with only 6 employees so maby just a reseller
Shenzhen Yangzi Power
Also called YZpower. Does not have a website but a facebook page. The two model in the image ive had some experience with but they are not good quality but they works. The fans are very loud and the price is ultra cheap. You usually find them very cheap on aliexpress.
Guangzhou Donglong Electronic Co.,ltd
Aka DLon. Probably a small manufacturer. They have a lot of production, testing an shipping videos on their facebook. Founded in 2014 from former Guangzhou Yixiu Lvdian Energy Technology Co.,ltd.
They are now famous for using fake (plastic) Rca connector that comes with make bike X. It melts and get stuck in the charging port! Also their webbsite seems to be of the same quality!
Wuxi Sans Electronic Co.,Ltd.
One of the larger manufacturers of battery chargers 24-72V. Started in 2008 and sells millions of chargers to 100s of ebike manufacturers. They claim to be “the leader of 36V bike charger manufacturer” and that might be true. We see them often used often 500s times or more and still work fine. Sure they have a little bit lower voltage after so many cycles but they should last about 10 years or so.
Phylion? Uses Sans Wuxi for 42V/2A and Modiary for 42V4A
Tangspeed. Sold on aliexpress, probably Gojusin.
Jnenconn Nicety. Sold on aliexpress, probably Gojusin.
Dongguan Changbao = probably reseller.
Dongguan Angdi Technology = Reseller of Modiary and other brand.
Guangzhou DongLong Electronic = Maby a reseller.
Dongguan Wali Electronic Co., Ltd. = Reseller of Donglong under names like Wate and Wadouks on aliexpress.
Yucoo Network Equipment = Makes mostly power supplies but also has sells Donglong chargers.
Dongguan Xinsu Global = Reseller? Look at their PDF. They photoshoped their logo on a building, claims to working with bosch and that they are designed in USA. They might produce some small adapters but claiming to work with General Motors! They also claim they have military class battery chargers! They also 21 certificates to prove how “geniune” they are!
