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