Use any bicycle pump, air compressor or local service station to refill this environmentally-friendly air
horn. One charge puts out more than 40 blasts of sound at 115db. It meets all U.S. Coast Guard
regulations and conveniently fits in a drink holder. Noncorrosive and
nontoxic because it uses no chemicals and no batteries, just compressed air.
On the serious side, the Eco-Blast is the first truly earth friendly device I have had the privilege of owning in a long time. I took it with a 'grain-of-salt' when I first saw it... a plastic valve on a soda pop bottle... However, this is fantastic little horn really does blow and loudly. I compared it to my small hand held that uses replacement cans and this one took the flag, hands down... adjustable volume\u2026 large reservoir\u2026 light weight\u2026 and it does not get \u2018super hot\u2019 in sunlight! It fits in my on-board cup holders and refills easily with one of my boys old sports ball pumps that fit on it in a heartbeat. No waste going to the landfill and no extra money out of my pocket for \u2018air\u2019\u2026. What more can I say other than the \u2018beauty of this beast is more than skin deep\u2019 I may even try taking this as a 'first defense' noise for driving off bears that get too friendly up in Alaska.
