In this article I will share why the RRSKIT Shimano Di2 USB-C Charging Adapter is a no brainer to have in your toolbox. In my professional life I’ve almost all mobile devices and accessories have moved to USB-C charging, and if not I’m using a USB-C to the device specific adapter.
Key features RRSKIT Shimano Di2 USB-C Charging Adapter
On the product page of the RRS Kit Shimano Di2 USB-C Charging Adapter on the AliExpress webshop you can read the following description:
Compatible with Shimano 12-speed Di2 systems The RRSKIT Bike Battery Charger Adapter is specially designed for electronic derailleur systems from Shimano 12-speed Di2, including models such as Dura-Ace R9200, Ultegra R8100 and 105 R7100.
Perfect addition for Di2 bikes This Shimano charging converter ensures reliable charging of the bike battery and is ideal for use with electronic shifting systems from Shimano. Versatile colors available
Available in different colors such as Apple green, Bianchi Green, Black, Light blue, cherry blossom pink and lavender, for a personal adjustment to your bike.
Compact packaging and lightweight The packaging has dimensions of 10 x 10 x 4 cm and weighs only 0.050 kg, making it easy to store and transport.
Sold individually Each package contains 1 piece of the RRSKIT Bicycle Battery Charger Adapter, suitable for direct use or as a spare part.
Origin: Mainland China The RRSKIT adapter comes from Mainland China and is manufactured according to standardized specifications for reliable performance.
No hazardous chemicals The product does not contain highly hazardous chemicals, making it safe for use and storage in various environments.
The key feature is that it is a relative cheap alternative to have a spare Di2 charging option available based on the USB-C standard that a lot of people carry around. The RRSKIT Shimano Di2 USB-C Charging Adapter is super compact 2.0 x 2.5 x 1.5 cm so I could put it in my totsi cycling saddlebag or Craft Cadence Essentials Case. I’ve also put one in my toolbox, so I never have to think about taking the original Shimano Di2 charging cable with me.
The price point is a key feature, which is significantly less than the original Shimano Di2 EW-EC300 charging cable, which I normally use in my home garage. The Shimano Di2 EW-EC300 Cable will cost you around € 34,00. So you can afford a couple of spare RRSKIT Di2 USB-C Charging Adapters for the same price.
The RRSKIT Di2 USB-C Charging Adapter also comes with an RRSKit sticker and a short rubber lanyard so you can attach the Di2 USB-C Adapter to it. It don’t use that rubber lanyard at all. 😉
Concluding thoughts and wrap-up
The price point of the RRSKIT Shimano Di2 USB-C Charging Adapter € 14,00 and you will see variations from € 7,00 – € 28,00. For me it is an item you slip into your toolbox, which you take on on a short trip with the minimum you want to pack. The RRSKIT Di2 USB-C Charging Adapter doesn’t take up any space and is super compact, you can even put it in your saddlebag.
I also have a U-Green USB-C to Micro USB Adapter for the Garmin Varia RTL515. So basically I connect 2 USB cables to an old Anker powerbank and make sure that the Shimano Ultegra R8170 internal battery and the Garmin Varia RTL515 and charged.
