タブレットは生徒に1台ずつ与えられており、教室後方には高速充電可能な機器も新たに備え付けられた。
I have a little bit doubt about the proper interpretation of the sentence.
機器も新たに means a new device, but 新たに備え付けられた means newly installed/installed recently (I personally think it might be the proper one).
One other thing, 高速充電可能な機器も in my interpretation is a fast charging device, so 可能な can be omitted if I translated the sentence in English.
Thank you for your kind guidance in advance.
