About Us
The technical development progress of solar charger
Foreword
We, Hangzhou Hongjia Technology Co., Ltd. have a high efficiency work team which includes renowned university's professor and doctor from mainland of China, Taiwan and South Korea, and many professional technicians. The solar power battery chargers and solar power banks we developed can be called the world's earliest and best of its kinds; it has excellent performance of electronic design and beautiful practical design which is the best compare with similar products in many ways.
Product Development History
1. In October 2000, we put forward the demands of multifunction, and use rechargeable batteries that can be recharged repeatedly, in order to achieve user-friendly, energy saving and environmental protection.
2. In July 2001, the first prototype of the external installed multifunction portable power supply was presented.
3. In September 2002, our products had been highly praised in high-tech Fair in Shenzhen China. Three months after then, many similar products graphics design and leaflet came in public.
4. In February 2003, the first portable mobile power W6000 was presented in public.
5. In December 2003, the portable mobile power W6000 was modified by adding power display.
6. In March 2004, the portable mobile power W6000 was modified to change its output voltage switch-button interface into more different voltage outputs.
7. In May 2004, the first handmade prototype of small portable mobile power W3000 was presented.
8. In August 2004, the solar energy panels of W6000 portable mobile power were modified to use polysilicon to replace the original monocrystalline silicon. And its batteries were changed from Lithium batteries to Lithium polymer batteries.
9. In August 2005, the moulds design of the small portable mobile power W3000 had been completed and used for production.
10. In September 2005, both W6000 and W3000 portable mobile power were designed with protection of over discharge functions that pass the quality test.
11. In October 2005, the portable mobile power W6000 was modified to increase a 19V output.
12. In June 2006, the portable mobile power W3000S was modified to increase solar energy charging function.
13. In September 2006, the W3000S mould was completed.
14. In October 2006, the products have been completed with modifications to meet with the ROHS standard.
15. In October 2006, we have performed the security experiments on W3000, W3000S and W6000 with high-altitude fall, puncture, extrusion and other methods. the test results showed no explosion, and no combustion.
16. In August 2007, portable mobile power W3000S, W6000 were modified to more compact in design and more convenient for carrying.
17. In May 2008, solar power bank SP-4000 was modified from W6000 with improved functions and sophisticate design.
18. In June 2008, solar power battery charger SP-3000 was developed with improved functions from W3000S and with more advanced appearance.
19. All products obtained the certification of CE, EMC, and ROHS in June 2008.
After eight years, our company's products get the excellent results through numerous experiments, market researching and various mobile products researching. Company also can provide customers electronic battery technical design.
