Is there a good replacement for "both" in this sentence? (Which refers to three items.)

Question

This sentence refers to three items:

You can bring both the smartphone, laptop and power bank charger in your hand luggage.

I've seen from this answer that "all" is more correct when referring to three or more entities. However, "all" doesn't work in this sentence.

1. Is the sentence alright as it is?
2. If no, can I replace another word for "both"?
3. Or, do I have to restructure the sentence completely?

Answer 1

1. I don't think so since both specifically refers to two things.

2. I would consider omitting both.

   You can bring both the smartphone, laptop and power bank charger in your hand luggage.

   You can replace both with all of them, all three, all three of them, the three, etc., but it would require some extra punctuation.
   Example.

   You can bring all three (the smartphone, laptop, and power bank charger) in your hand luggage.

3. From context, it's clear which three items we're talking about, so you can simply write, for example,

   You can bring all three in your hand luggage.

   Lastly, you can use both, but it takes some restructuring.
   Example.

   You can bring both the smartphone and the power bank charger, and/plus/(in addition to) the laptop in your hand luggage.

   I paired the smartphone and the power bank charger since those are the two new items.
