Great question and something most people forget to ask before booking!

So it honestly depends on the type of tempo traveller you go for. Standard tempo travellers usually have a basic music system but charging points can be limited, sometimes just one or two near the front seats which is not very practical for a group of 12 people with everyone needing to charge their phones.

Luxury tempo travellers are a different story. Most come with individual charging points, a proper music system with Bluetooth connectivity and sometimes even a screen. If you are going on a long trip this makes a huge difference especially for overnight journeys.

My suggestion is always confirm this with the operator before booking and ask them to show you the vehicle once. Do not assume it is included.

When you go for tempo traveller hire in Delhi make sure you specifically request a vehicle with charging points, good operators will always accommodate that
