AstroAI Jump Starter Power Pack with Air Compressor, 1500A 12V Portable Car Battery Booster Jump Starter and 150PSI Tyre inflator Power Pack with Emergency Light, LED Display

Holds charge well. Works first time every time.Also has a decent tyre inflator and task light.A must have for peace of mind.

The AstroAI S8 Jump Starter, Tyre Inflator and Power Pack is a very well made unit. It is quite bulky but it is easy to use and not all that heavy. Setting the Tyre Pressure required is easy and it cuts off automatically when it hits the set pressure. Jump starting is just as simple and the case is robust and connectors are well made. Very happy with this purchase. Trying to register was not so easy the web site is not user friendly. Still that is a minor issue in the scheme of things, Amazon support should cover it if needed.

I've tested this air compressor/jump starter combo fairly rigorously over the past few months and I'm overall quite impressed with such high performance in a tidy, compact package.Pros- Robust compressor that is more than capable of topping up several car & van tyres on one charge.- The PSI/BAR value seems accurate to +/- 1PSI when compared with my manual pressure guage.- Included ttachments so you can inflate toys, footballs, gym balls etc.- Charges via USB-C, if you have a phone charger, you can probably charge this device.- Flashlight is very bright and I've already found it incredibly useful when topping up a tyre at night.- The jump start feature has been tested on a dead 12v battery (reading 10.2 volts), and successfully allowed the engine to crank and alternator to start charging.Cons- All plastic construction, designed to look rugged but is infact slightly cheap. It creaks when flexed. The hose attachment is thin metal and doesn't give a great impression of longevity, although I've had no breakages despite using it frequently.- Attachments tend to be fairly loosely clipped to the unit, however it does come with a handy pouch to store everything in so this isn't a huge issue.- Buttons are rubberised, which provides extra grip and some rain resistance, but this texture tends to become sticky and horrible to use after a few years, especially when stored in a hot, sunny location, such as a car!- The battery is probably only capable of pumping up one FULLY deflated tyre, before needing a recharge. But I suspect this would be fine for most.- The included charging cable is quite short (although you can use any third-party USB-C cable.- The compressor is pretty loud, possibly louder than my old 12v compressor.- The jump start feature has a "boost" button when the car battery voltage is too low, as "boost" mode bypasses the various safety features on the charger, it should only be used if necessary. This is mentioned in the manual but it seems that some may misinterpret the boost button to charge the battery faster & risk putting too many amps into the battery/car unnecessarily. Perhaps they should reword this button to "bypass" instead.All in all, I'd recommend this handy device, especially when on sale. It has served me well over the past few months, I've bought some for friends/family as gifts and they've all been well received. I was skeptical that a cordless device would ever be as reliable as a 12v compressor, but I've been pleasantly surprised!

Excellent gadget and does exactly what it says on the advert. I can pump up the car tyres or jump start the car with ease

Excellent

I bought this product to keep my car tyres at even pressures. It works really well. The only thing I would say is you need to keep an eye on the pressure setting when going around each tyre. It always jumps back to 36psi. It could do with a handle like a strap or something other than that I am very happy with it.

Excellent product only used once so to start car with battery 100% flat started effortlessly in seconds.

When package was opened I was initially sceptical that such a light charger was really heavy duty enough to jump start a main battery on a motorhome. However the charger performed perfectly first time ...so dont be fooled by how heavy it is. Keeps charge well...highly recommend
