Eto ang gamit ko (bought at Ace for around Php1,7k):





Have only used it for topping up so far. Wala siyang deflator so kung na-overinflate ka sa gas station air fill-up, manually mo muna siya babawasan ng hangin saka inflate to your preferred psi. Features include the digital tire pressure gauge and a 5V USB outlet for charging your electronic devices, though you still need to plug it to your car's 12V cigar lighter outlet.

Cons include the 40~50 psi max pressure and not being able to inflate from flat. Haven't tried to inflate a flat but I think it's doable as long as there's 5~10 psi left and you inflate in short bursts.

There's a higher capacity and more heavy duty model though it's already around Php2.3k++ yata:
