Diwali decor runs on one thing, and that's a plug point nobody put in the right place. The lights go up on the balcony, the switch sits in the hall, and the gap between them is six metres. A heavy-duty board closes that gap, and it takes the load without heating up. It works for string lights, for a diya warmer and for the music system too. But the cable thickness does matter, for a thin cord will not carry a full balcony.

A good board is easy enough to keep using for the rest of the year. Some come with surge protection, some with individual switches, while others roll out on a reel too. Also, the wattage matters a lot. If you are running lights across two rooms, go for 2500W rather than 1440W. Also, check the cable length; two metres rarely reaches where you want it. So here are the 5 best extension boards that you can buy on Amazon.

Top 5 Heavy-Duty Extension Boards For Diwali Decor Lights Under ₹1,600

1. Belkin 6-Socket Extension Board with Surge Protector

Price: ₹1,599 | Customer Ratings: 4.5/5

This board by Belkin runs six universal sockets with surge protection built in. The cable is heavy-duty at 2 metres, or 6.5 feet. Overload protection kicks in before anything overheats. Belkin gives it a five-year manufacturer warranty, which is almost nothing else here matches. The body is grey, and it runs on 220 volts.

Key Features:

  • Six universal sockets
  • Surge and overload protection
  • Five-year brand warranty

Why Buy: 

If a power cut and sudden surge worry you, this is the board to pick. Six sockets also mean the lights, the speaker, and the phone all go in together. Five years of warranty is long enough to cover several Diwali seasons. It's the most protected board.

2. Palfrey Extension Board with Two 16A Sockets and MCB Switches

Price: ₹1,186 | Customer Ratings: 4.2/5

Palfrey builds this one for 16A rather than the usual 6A. There are two 16A sockets with safety shutters and two 16A MCB switches. The cable is 2.5 sq mm, 3-core, and runs 2 metres. It handles 3000 W, and the plug has an indicator on it. The colour here is white.

Key Features:

  • Two 16A sockets
  • MCB safety switches
  • 2.5 mm² cable

Why Buy: 

Go for this one when the load is big and ordinary boards have tripped on you before. MCB switches also cut the supply themselves instead of melting a fuse. Safety shutters keep small fingers out of an open socket. It's the heaviest-duty board here.

3. Honeywell Surge Protector with 4 Universal Sockets

Price: ₹1,039 | Customer Ratings: 4.5/5

Honeywell puts a 15000 Amp surge figure on this one. There are four universal sockets and a master switch on the body. The cord runs 2 metres, and overload protection works automatically. Honeywell adds a three-year manufacturer warranty and a device-specific warranty. It doubles as a surge protector.

Key Features:

  • 15000 Amp surge guard
  • Automatic overload protection
  • Master switch control

Why Buy: 

Anyone plugging a television or a laptop into the same board will want that surge protection. A master switch also kills everything at once when you go to bed. The device warranty covers what is plugged in, not just the board. Keep it indoors rather than out on a wet balcony.

4. Cablet Extension Board 2500W with 6 Sockets and 4.5-Metre Cord

Price: ₹879 | Customer Ratings: 4.6/5

Cablet gives this one a 4.5 metre heavy-duty cord, the longest here bar the reel. Six universal sockets each have their own switch. It is rated 2500W at 10A, with an LED indicator on the body. Cablet sells it as a power strip and a spike guard together. It suits both home and office.

Key Features:

  • 4.5 metre cord
  • Individual socket switches
  • 2500W at 10A

Why Buy: 

You should look at the individual switches if half your lights stay off all day. A long cord also saves you running a second board off the first. 2500W is enough for a balcony string and a diya warmer together. Nothing else here runs a switch on every socket.

5. Havells Cosmo Reel Extension Board with 5-Metre ISI Cable

Price: ₹325 | Customer Ratings: 4.4/5

Havells winds this one onto a reel instead of leaving the cable loose. The cord is 5 metres, ISI-marked, and it rolls back in smoothly. There's a 3-pin socket plus two 2-pin universal sockets, with a master switch. It is rated 6A at 1440 watts on 240 volts. An LED indicator sits on the body.

Key Features:

  • Five metre reel
  • ISI-marked cable
  • Master switch indicator

Why Buy: 

A reel makes sense when the board gets packed away the day after Diwali. ISI marking also tells you the cable has been tested rather than just sold. The master switch means one press shuts the whole string down. 

A balcony full of lights is only as safe as the board feeding it, and these five take the load. For protection, Belkin stacks six sockets behind a surge guard, while Honeywell quotes 15000 Amp of its own. If the load is heavy, Palfrey runs 16A sockets with MCB switches built in. Cablet stretches to 4.5 metres with a switch on every socket, and Havells winds 5 metres onto a reel.
