    Potente e sicuro

    Ho avuto la possibilità di ricevere questo avviatore Avapow per avere una sicurezza in più durante i viaggi e devo dire che è uno di quegli articoli che ti fanno stare tranquillo. L’ho testato due volte su una batteria completamente scarica e ha rimesso in moto l’auto in pochi secondi!
    La potenza si sente: 3000A non sono scherzo, e riesce ad avviare senza problemi anche motori grossi.
    Possiede due modalità, una normale e una per batterie completamente morte utilissima quando il motore proprio non dà segni di vita,inoltre, le pinze intelligenti e i vari sistemi di protezione (contro cortocircuiti, polarità inversa, surriscaldamento, ecc.) fanno sentire davvero al sicuro anche chi non è esperto.
    Il display grande e chiaro è comodissimo, mostra tutto in modo leggibile anche al buio,e non è solo un booster: può caricare smartphone, tablet o altri dispositivi tramite le porte USB e USB-C,una funzione davvero utilissima.
    La torcia integrata è un'ulteriore plus soprattutto se capita un’emergenza di sera o in strada.
    Il tutto arriva in una custodia robusta e ordinata, così è sempre pronto all’uso.
    In sintesi: compatto, potente e super affidabile,da tenere sempre nel bagagliaio utilissimo al bisogno!

    Handy car battery starter

    This is a device every household should have! It enables you to jump start a stalled car battery easily and without needing another vehicle next to it.

    I was a little confused initially by the 3color bands that appear on the screen when you turn the device on. Reading the instructions explained that these basically tell you the charge level of the device battery!

    So instead of the traditional percent display, you see the 3 colorful bands. If all three (red, orange and green) are lit, then the device battery is fully charged. If it’s less than 2/3 charged, then the green band will disappear. If the battery is low, then only the red band is visible.

    The screen has other functions. For example, when you connect the device to a car’s battery to jump start it, then it will show “Ready” so you know you can proceed and switch the ignition on.

    If things go wrong, the screen will show an error case to let you know what happened. A handy card explains what each error code means.

    The handy device also has USB ports in case you need to charge your electronics. It also have a unique DC port that you can plug the included wire and you’d have a very handy 12V outlet to use for site compressor for example!

    In addition, the device also has an LED flash light that cycles from steady light to flashing to SOS signal.

    My best jump starter! Hands down!

    Pack is powerful. It started a vehicle that four jump packs together could not. It's a lot heavier and more substantial than most portable packs of its kind, and it's designed for bigger engines, so it's definitely a lot more liable to work for your car or SUV or truck. The Cable length could be a little bit longer in my opinion, but otherwise, this is the shizzle. It works perfectly, it's durable, it holds a charge for a good while and you get more jumps from a charge, and it's just a simple to use as the others of this type. It's really pretty flawless. Highly, highly recommend!

    Started a Truck Without Hesitation

    This jump starter powered up quickly and the display is clear and easy to read. I tested it on a truck with a weak battery and it started without hesitation. The clamps feel strong and the included light has multiple brightness settings. The case is bulky but it makes sense given the power capacity.

    Heavy-duty jump starter

    At first impression, this jump starter gives a strong sense of durability, making it well-suited for tough outdoor use. It’s packaged in a rugged zippered case that keeps everything neatly arranged.

    The jump starter itself features a bright, easy-to-read display. The clamps feel sturdy and the jaws open wide. A built-in LED light provides some illumination for nighttime or emergency situations.

    All in all, it’s a well-designed and dependable tool that balances practicality with durability. It’s an excellent piece of gear to keep in the car, offering both reliable emergency starting power or as use as a power bank. The jump starter is made very well, but the price point for a jump box, even one strong enough to start a diesel, seems high. There are other similar boxes available at a far more affordable price.

    Easy to use jump box

    We have used this to jump a 2020 Toyota Camry and a 2014 Lexus LS600h within about two weeks of each other. The jump box was easy to use and more convenient than having to deal with the traditional and cumbersome jumper cables. We haven’t had to charge it yet, but will probably do that so as to be prepared for the next time around. The jump box seems well constructed and is definitely a good value if you don’t want to be stuck on the side of the road or in a parking lot waiting for your roadside assistance or a friend to bail you out.

    Does the job well!

    Already used it twice. Worked great. What a difference not having to hook up jumper cables; make sure the other vehicle engine is reving; etc. Great purchase; great value for the price. (Good price, too)

    It doesn't work on a diesel engine

    I bought this to keep with my ford 7.3. I recently needed it to jump my dead battery. It was fully charged and wouldn't crank engine. Very disappointed and waste of money.

    Great but not 4x great ...

    I have to ding this unit just for the price vs other comparable jump starters. That's it, aside from that, it is perfect. It has a sturdy body, more rugged than any others I own or have owned. I own ones that lasted 3 months. This one is solid. However, it is 3x+ the price. At 44wh, you are not getting 3x the battery as any other jump starter out there. So that all aside, the jumper connectors are more robust than others ... I had one inferior set fail on me mid-jump this winter. So I also like to measure batteries that I get ... this one tested 13.7mOhms and 186 CCA ... that's .... not 5000A lol. So just compare it to other jump boxes and make a choice.

    Would not charge

    I bought this based on the large number of 5 star reviews. However it was defective right out of the box. It would not. Garage even after 24 hours. The company has great service when there is a problem

    lifesaver

    This thing is a lifesaver. My wife had some real bad corrosion and buildup on the battery terminals of her car. I cleaned them up for her but forgot to charge the battery. The next morning when her car wouldnt start I hooked this guy up and seconds later she was off. It couldnt have taken more than 30 seconds. I bought a second just for her.

    Excellent battery for starting batteries - powerful, easy to use and reliable

    I’m no expert on technical and mechanical things - not a worry to me - but it does mean that when I buy a product like this it just needs to WORK. No messing about, no complicated instructions, just plug and play.
    Happily, this battery starter kit fits the bill perfectly.
    Keep it charged, connect it up, turn it on, engine on and get that battery kick-started.
    The battery is powerful (5000A, 12V), it’s suitable for petrol and diesel vehicles, the clips are sturdy, the cables re-informed, the display bright and clear, the safety light is a beast, and there are even additional USB ports for charging other items (ie. phones) that might help keep you safe if you’re stuck out in the sticks. It won’t need charging up every time as it has a high capacity when fully charged.
    It’s easy to use and excellent value given the peace of mind it brings.
    Very please with this and with the added sense of safety and convenience it brings for our family when out and about.
