Power Cut Kit: What to Keep Charged and Ready in Sri Lanka

Power cuts happen — planned maintenance, weather, a fault down the road. None of that is dramatic if the house is ready, and the whole kit costs less than most people assume.

Here’s the honest version: four things matter, in this order.

1. Light you don’t have to hunt for

The most useful light is the one already charged and in a known place. A phone torch works for two minutes and then you want your phone back.

• A rechargeable lantern is the best single buy. It lights a whole room from a table or a hook, and runs for hours on a low setting — which is what you actually need, rather than a searchlight that empties itself in an hour.
• A torch is for moving around, going outside, or checking a fuse box.
• A head lamp keeps both hands free, which matters if you’re cooking or fixing something in the dark.
• A solar-rechargeable light makes sense as the second light. Solar charging is slow and weather-dependent, so it’s a backup to your backup — but for a long outage, being able to recharge without mains at all is the whole point.

Keep it plugged in and topped up. A dead lantern in a drawer is not a power-cut kit.

2. A power bank that’s actually charged

For most households the power bank is not for emergencies — it’s for daily use, and it happens to be there when the power goes.

• 10,000mAh refills most phones about twice. It’s the practical everyday size.
• 20,000mAh and up gives roughly four phone charges, or charges a tablet too. Heavier, and slower to refill itself.
• Check the output, not just the capacity. A bank with USB-C Power Delivery will fast-charge a modern phone; a cheap 5W one will trickle.

The habit matters more than the specification: top it up when it drops, not when you need it.

3. Air, if you’re somewhere hot

In a humid climate an outage stops being an inconvenience the moment the fans stop, especially at night or with small children in the house.

A rechargeable portable fan runs for hours off its own battery and is the single most-appreciated item in this list on a still, hot evening. The small clip and desk models are enough for one person; the larger turbo-style units move real air across a room.

4. A way to stay connected

If you work from home, this is the one that costs money when it’s missing.

• Your phone’s mobile data is the simplest fallback — but check your phone is charged first, which is what the power bank is for.
• A pocket WiFi router has its own battery and keeps a small network alive through a cut. That’s why it doubles as an outage backup rather than being a single-purpose purchase.
• Your home broadband router will not run from a normal power bank. Most take 12V through a barrel connector, not USB. Assume it goes down with the mains and plan around mobile data.

The ten minutes before a scheduled cut

If you know it’s coming:

1. Top up the phone and the power bank — and the laptop, which is its own large battery.
2. Fill a jug or two of water if your supply depends on a pump.
3. Put the lantern where you’ll be, not where it’s stored.
4. Cool the room down first — fans and air conditioning now, so the room starts cooler.
5. Unplug what you care about, or move it to a surge-protected extension. Return of supply is harder on electronics than the outage itself.

When power comes back

Give it a couple of minutes before plugging sensitive equipment back in, and use a surge-protected extension for anything expensive — a desktop, a TV, a router. It’s a small cost against a repair bill.

If you regularly lose supply, an extension lead with surge protection is worth having on every desk rather than one shared through the house.

The short list

What	Why	Size to look for
Rechargeable lantern	Lights a room for hours	Multiple brightness modes
Torch or head lamp	Moving around, hands-free work	USB rechargeable
Power bank	Two or more phone charges	10,000mAh daily, 20,000mAh at home
Rechargeable fan	Sleeping through a hot outage	Battery-powered, not USB-only
Pocket WiFi	Staying online	Built-in battery
Surge-protected extension	Protects gear when supply returns	Enough sockets for one desk

None of it is exotic, and most of it is useful on an ordinary day too — which is the point. A kit you only touch during an outage is a kit that’s flat when the outage arrives.
