Kero: Outage-Ready Rechargeable Task Lamp (Product Concept)

Kero is a rechargeable task lamp that keeps working when the power doesn't. The problem: when the grid cuts out, light and phone charging fail at the same moment, and people end up juggling a torch, a power bank and a desk lamp that each do one job. Kero is designed for students, remote workers and families who work or study in the evening and can't plan around outages. The goal is one object that lives on the desk every day, so it is already charged and within reach when the lights go off. One fold, three jobs. The arm and light bar fold flat against the body, and folding it changes what the lamp does, so there is no mode menu to learn in the dark: - Task: arm up, light bar over the page for directed, glare-free light - Lantern: arm folded, the diffuser ring lights the whole room; carry it by the strap or hang it from a hook - Power bank: a USB-C port at the back charges a phone from the same battery Concept size: Ø90 x 160 mm folded, 310 mm open, with a 150 mm light bar. Materials and finishes: injection-moulded recycled ABS body with a fine matte texture, opal polycarbonate diffuser ring, extruded and anodised aluminium arm that doubles as the LED heat sink, one knurled dial (press for power, turn for brightness), silicone non-slip foot and woven nylon strap. Colourways: Petrol, Graphite and Sand. Target spec (design targets, not tested): 10,000 mAh user-replaceable lithium-ion pack, up to 400 lm with stepless dimming, 2700/4000/5700 K, USB-C in and out at 18 W, and an outage mode that switches on at low brightness when mains charging drops. Included: concept overview, three-mode diagrams, views and dimensions, and a materials and target spec sheet. Concept dimensions are to be refined in CAD.
