Catch the stars in a jar. The Star Catcher is a mason-style glass jar printed with a glittering map of the constellations — and hidden in its lid is a small solar panel. Leave it in a sunny spot during the day and it quietly banks the sunshine; then, when darkness falls, the jar automatically lights up from within, and the whole night sky glows softly blue on your shelf, desk, or nightstand. No plug, no charging cable, no battery swaps — just sunlight in, starlight out.

There's real science packed into this little jar, which is exactly why we love it. A photovoltaic cell converts daylight into electricity, an included rechargeable battery stores it, and a light sensor waits for the room to go dark before switching the lamp on — three clean energy concepts working together every single day. A full day's charge (about 8–10 hours of sun) delivers 6–8 hours of gentle starlight, making it a soothing night light for stargazers young and old, and a genuinely lovely gift for anyone who'd like to fall asleep under the constellations.

Features:

  • Solar-powered: the panel in the lid charges the lamp with nothing but daylight
  • Lights up automatically when the room goes dark
  • Glows for 6–8 hours on a full charge (about 8–10 hours of sun)
  • Rechargeable battery included — no plugs, cables, or battery swaps
  • Real glass mason-style jar printed with a detailed constellation star map
  • Simple on/off switch under the lid
  • Approx. 19 cm (7.5 in) tall — perfect for a nightstand, shelf, or windowsill
  • An eco-friendly night light and a beautiful gift for stargazers

How It Works

Three small pieces of technology take turns through the day. First, the solar panel in the lid converts daylight into electricity — set the jar in a sunny spot (a windowsill is perfect) with the panel exposed. Second, the included rechargeable battery stores that energy, filling up over about 8–10 hours of good sun. Third, once you've flicked the switch under the lid to ON, a built-in light sensor watches the room: when darkness falls, it automatically turns on the lamp, and the constellation map printed on the glass glows to life for 6–8 hours. At sunrise, the cycle simply starts again.

The Science Behind It

  • Photovoltaics: how a solar cell turns light directly into electrical energy
  • Energy storage: why a rechargeable battery is the bridge between daytime charging and nighttime glow
  • The dusk sensor: how a light sensor detects darkness and switches the lamp automatically
  • The constellations: the star patterns mapped across the jar — a tiny planetarium for your room

Perfect For:

  • A calming night light for bedrooms and nurseries (placed safely out of little hands' reach — it's glass)
  • Stargazers, astronomy fans, and celestial-decor lovers
  • A hands-on conversation piece about solar energy
  • Birthday, holiday, and housewarming gifts
  • Anyone who'd like to drift off under the stars

Setup & Use

  • Unscrew the lid and flick the on/off switch to ON.
  • Charge it by placing the jar in a sunny spot with the solar panel facing the light — a bright windowsill works beautifully.
  • Once charged, put it wherever you want stars: in the dark, it lights up on its own.
  • It's a real glass jar — handle with care, and place it where it won't be knocked over.

Frequently Asked Questions

How does it charge? Sunlight. The solar panel in the lid charges the included rechargeable battery — no plug or cable. About 8–10 hours in good sun gives a full charge.

How long does it glow? Roughly 6–8 hours on a full charge — enough to shine through bedtime and beyond.

Does it turn on by itself? Yes. With the switch set to ON, a built-in light sensor turns the lamp on automatically when the room gets dark.

Do I need batteries? No — a rechargeable battery is included, and the sun keeps it topped up.

How big is it? About 19 cm (7.5 in) tall and 10 cm (4 in) across — a classic large mason-jar size.

Is it glass? Yes — it's a real glass jar, which is part of its charm. Handle it with care and keep it out of reach of very young children.
