Portable solar for ebike

Hi all. New to solar and hoping for some guidance building a portable solar charging system for an ebike and a separate, smaller battery pack.

I have the following components:

160w PowerFilm foldable solar panel with 15ft. SAE to bare lead extension cable

• Wattage: 160
• Operating voltage: 28.3v
• Current: 5.7a

Genasun GVB-8-WP Boost charge controller

• Max PV voltage range: 0-60v
• Max battery voltage range: 9.5v – 54.2v
• Max input current: 15a

E-bike battery:

• Capacity: 48v, 19.2ah, 921.6wh
• Limited charge voltage: 54.6v
• Charging current: >= 5a
• Input connector: 5.5×2.1mm barrel connector

Nitecore 10k power bank

• Capacity: 10,000mah
• Input: 5v/2.4a, 9v/2a

My questions are:

1. What are the recommended connector types? I’m seeing a lot of different connector types such as SAE, MC-4, Weatherpack, Anderson power pole, etc., and not sure which ones would be best for this application?

2. I need to be able to charge both the ebike battery and the power bank, preferably simultaneously but sequentially works as well. I was thinking of connecting a 12v cigarette lighter adapter to the 15ft. extension cable coming of the panel, but the cigarette lighter to USB adapter I’m looking at is rated for a max voltage of 24v. With the panel rated at 28.3v, would I burn up the USB adapter? Also, using the cigarette lighter connector means I would need the USB adapter for the battery bank as well as another male adapter to connect to the Genasun charge controller. Is there a better, lighter, less bulky way?
