Nouzová sada pro výpadek proudu

The signal whistle is surprisingly loud for its size, and the flashlight cuts through a dark room easily. Used it during a brief blackout last week and the power bank saved my phone from dying. For the price, this kit covers the basics without taking up much space.

I tossed this in my go-bag and was relieved the power bank actually held a charge after sitting for months. The whistle is loud enough to feel useful in a real blackout, not just a keychain toy.

The mini flashlight is surprisingly bright for its size, and having the single-use power bank means my phone won't die during a long outage. I keep the whole kit in my kitchen drawer for easy access.
