Tiny, rechargeable keychain light with surprising punch — the i1R 2 EOS delivers a clean, useful beam in an ultra-compact package, perfect for keys, pockets, and everyday carry. Quick summaryThe i1R 2 EOS offers two modes (150 / 5 lumens), a built-in rechargeable battery that charges via micro-USB, and an ultra-compact aluminum body (≈44 mm / 1.73" long, ~12–14 g). Why it’s useful Pocket-and-keychain friendly — tiny and featherlight, so you can carry it every day. Rechargeable convenience — no disposable cells: unscrew the tail to expose the Micro-USB port and top up quickly. Simple interface — twist-head on/off and mode change (high for bursts of light, low for longer use). Weather-ready — IPX8 water resistance for worry-free carry in rain or outdoor use. Key specs (at a glance) Output: 150 / 5 lumens. Runtime: ~15 minutes on high, ~6 hours on low (high mode is for short bursts). Beam distance: ~40 m (≈131 ft). Battery: built-in rechargeable Li-ion (micro-USB charging). Size / weight: ≈44 mm (1.73") length; ~12–14 g (0.46–0.5 oz). Good to know The high mode gives bright, immediate light but is intended for short bursts — if you need longer continuous run time, use low mode. Reviewers note the strong burst capability but limited high-mode duration. Because the battery is internal, avoid over-unscrewing the body to preserve the waterproof seal. Bottom lineIf you want a fuss-free, rechargeable keychain light that’s tiny enough to forget you’re carrying it — yet bright enough to be useful when needed — the Olight i1R 2 EOS is an excellent everyday backup.
