What's the use of the て-form in this sentence?


While reading manga a character stole a power from another guy and said:

> ちょっとこいつの力を試してみたくてな。

I wonder what's the use of the て-form in みたい?. What would be the difference
with こいつの力を試してみたいな




It's an example of [te-form for reason](https://www.learn-japanese-
adventure.com/te-form-cause-reason.html), but the subsequent part ("I'm doing
this" or "I stole this power") is omitted because it can be inferred from the
context. In short, this te-form means "because".

  * 試す: to try it
  * 試してみる: to try it and see what happens (みる is a subsidiary verb explained [here](https://japanese.stackexchange.com/q/19038/5010))
  * 試してみたい: to want to try it and see what happens
  * 試してみたく **て** : **cuz** I wanna try it and see what happens
