Olight/Keychain
Minimalist rechargeable keychain light. The i1R 2 is tiny, twist-operated, and charges via USB. The simplest possible always-carry light.
Beam profile
Balanced, about 25° wide. A usable hotspot with enough spill to see around it.

Olight i1R 2 EOS/5 sources reviewed
A rechargeable keychain light smaller than an AA battery, operated by twisting the head: a little for low, further for high, back for off. Owners rate the build — the aluminium body has survived repeated drop tests and the keyring attachment feels secure — and are surprised by how much light it puts out for the size, enough to light a small room. Because it's mostly used in short bursts, owners report a single charge lasting a month or more.
The limits follow from a 70mAh sealed cell. High runs about twenty minutes. Charging is micro-USB at around 0.06A, which is slow but proportionate. The end cap feels loose while the charging port is open. And the sealed battery means the light is ultimately disposable — when the cell wears out, that's the end of it. Note it's been discontinued in the US in favour of the i1R 2 Pro.
