Extralink BT-4000 Emergency Radio – Power When the Power Goes Out

No electricity? You can still have radio, light and emergency power.

The Extralink BT-4000 is a clever all-in-one emergency radio designed for power cuts, camping, hiking, travelling and unexpected situations.

It combines DAB/FM radio, Bluetooth, a 4,500mAh power bank, LED torch, reading light and SOS alarm – and, most importantly, gives you several different ways to keep it powered when there isn't a wall socket anywhere nearby. Extralink

Four Ways to Keep It Powered

This is what makes the BT-4000 particularly interesting.

You can power or recharge it using USB-C, its built-in solar panel, the hand-crank dynamo or standard AAA batteries. Extralink

So during a prolonged power cut or while camping away from mains electricity, you're not completely dependent on its rechargeable battery.

Turn the Handle to Generate Power

The built-in hand-crank dynamo lets you manually generate electricity.

It's not intended to replace normal USB charging, but in an emergency it provides a way of generating power when your battery is flat and there is no electricity available.

There's also a built-in solar panel for another source of supplementary charging.

4,500mAh Emergency Power Bank

The internal 4,500mAh rechargeable battery can also be used as a power bank for compatible USB devices.

That could provide valuable emergency power for your smartphone when keeping some charge available for a call, message or other essential communication matters more than having a full battery. Batna sp. z o. o.

Radio + Bluetooth

Listen to DAB and FM radio using the telescopic antenna, helping you stay informed even when internet access isn't available.

When everything is normal, Bluetooth 5.0 also lets you use the BT-4000 as a portable wireless speaker for music from your phone. https://www.x-kom.pl

Light When You Need It

There's a built-in LED torch with three lighting modes, plus a fold-out reading/camping light underneath the solar panel.

The BT-4000 also incorporates an SOS alarm and warning light, adding another useful feature for emergencies or outdoor use. https://www.x-kom.pl

Why We Think It's Cool

Because this is one of those gadgets that you could leave in a cupboard for months – and be extremely pleased you bought when you actually need it.

Radio, Bluetooth speaker, torch, camping light, SOS alarm and power bank are useful individually.

But add solar charging and a handle you can physically turn to generate electricity, and the BT-4000 becomes a genuinely interesting piece of emergency technology.

ITsCool Verdict

We'd keep one of these at home for power cuts and emergencies, but it's equally useful in a camper van, tent, caravan or hiking bag.

And unlike a lot of emergency equipment, you'll actually use this one when there isn't an emergency – as a DAB/FM radio, Bluetooth speaker, torch and portable power bank.

When the power goes out, this little radio isn't ready to give up. Available from ITsCool.ie.
