I was skeptical about this at first - why on earth such a huge flashlight at one end?It's been well below zeroF here, and my tires needed a boost, so I hauled this out to do that.Whoops.Gotta charge it first.Plugged into kitchen USB jack. Checked next morning: Not full. Checked that night: Not full.It didn't reach full charge until the next day - so more than 24 hours.I saw later than it comes with it's own (separate) battery charger barrel style plug - presumably that will charge it faster.I have a garage compressor,with lots of soft hose....but even that is too stiff to handle at -14F!So this small portable unit may be Just The Ticket for Winter Tire Deflation.I set it on the ground next to the tire (tip, provide a place on the unit to put the tire stem caps!).Hm. Kind of dark there. Hey, it's got a light! Click....click - hey it can go (full) bright RED!! Yikes.But got it to 'normal' mode (there are several, some less bright) and then realized just how handy that light is: Point it at the tire, unreel the hose from it's onboard storage place, unscrew the cap, screw on the inflator, push the 'play' button (set pressure first) and walk away!!The light REALLY helps, esp with fiddly little things in dark areas in cold weather - WIN!It stops when it reaches the set pressure. Simple. (The light stays on.)The display is bright, large and easy to read from a distance (next tire, for instance).I would have preferred the snap lock as the default hose end, but having a storage place for it on board is more important (it comes with a snaplock extension, which you have to screw on, and has no place to 'hang out' when not in use.They do provide a rather nice bag for all the odd bits, clearly handy for camping and other inflatable uses.The battery can also be used as a charging station for other devices (plus being a light).If used regularly, the price is certainly reasonable...it looks like it will hold up really well.
