The Monstapump is a rechargeable inflator/deflator made by Zempire, designed especially for use with their Monstabed / Monstamat inflatable sleeping pads / mattresses. It can both pump air in and extract air to help with fast deflation / packing down. Features Inflation rate: around 450 litres per minute. Deflation: powerful enough to fully extract the air from a Monstabed mattress to make it much easier to roll up / store. Attachments / Nozzles: comes with multiple nozzles/valve adapters — specifically ones suited for the Monstamat / Monstabed valves, classic brass valves, Boston-valves, and even a small toy-inflator nozzle Carry case: includes a robust travel case for protection / storage. Specifications Maximum pressure: 0.7 psi (low pressure) — not for high-pressure jobs (e.g. inflating tyres) Dimensions: Approx 4.3 × 3.9 × 3.5 inches (~109×99×89 mm) Weight: Approx 1 lb 3 oz (~550-600 g)
