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 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 attachments so you can inflate toys, footballs, gym balls etc.- Charges via USB-C, so can be charged via a phone charger, or most devices with a USB port.- 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 quite 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 are 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!

Delighted with this piece of kit, holds the charge for ages, so quick to put air in my tyres and has auto cut out when psi is reached, I'd highly recommend it for keeping in the car for emergencies and my friend bought one for her teenage sons car for peace of mind, not used it to jump start yet so can't comment on that but as a air pump it's really really great, would highly recommend

Great item , value for money and arrived earlier than expected. Love the overall design

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

Best thing i ever brought.

I have not needed to use the jumpstart feature of this device so far, so I cannot comment on that as of yet.For tyre inflation however I tried it today and while it isnt the fastest inflator (I also have a Astro AI 12v tyre inflator which is a bit faster) it certainly isnt the slowest either, but it is battery powered. The pressure readout seems pretty acurate too against my other inflator. I expect this will be its main job, but while being slower than my other one it is more convenient with not needing to plug it in.
