Outdoor battery lights use a mix of battery types: disposable AA alkaline cells (some units use 2 or 4 AA), AA nickel‑metal‑hydride (NiMH) packs (examples show 2 AA or 6 AA NiMH), single lithium cells, and non‑universal lithium‑ion rechargeable packs. Some products include rechargeable batteries or a solar‑rechargeable battery.
Modes range from a simple on/off to multiple settings. Common options include high/medium/low brightness or high/low/nightlight for lanterns and portable lights; decorative strings often offer multiple effects or timers; some items provide a one-way on/off control (seen in a few wall or gallery lights).
Brightness in listings ranges roughly from about 10 to 1,200 lumens. Advertised run times vary widely by design and operating mode — roughly from 2.5 hours up to around 100 hours depending on brightness setting and product.
Rechargeable units typically recharge via USB (micro‑USB or USB‑C); some models are solar‑rechargeable. A few lanterns include a built‑in USB output or come with a charging cable so the light can charge phones or other small devices.
Common options include hanging displays for decorative lights, ground stakes for path lights, wall‑mounted fixtures, and handheld lanterns with carrying handles for portable use.
Features shown include micro‑USB or USB‑C charging ports (sometimes with included cables), built‑in USB outputs to charge phones, included rechargeable batteries (one listing notes a non‑universal lithium‑ion cell), and some products that mention a charge indicator.
