DEWALT DXAE20VBB Portable Battery Booster for Cars

Easy to use, nice n compact, paired it with dewalt xr 20v 4ah battery pack, used it to recharge and jump my 2009 bmw e90 several times already. Led light comes in handy, will be taking this as emergency roadside kit on trips. Charge button only works when hooked up to a battery; must let it fast-charge your dead battery for 3-5mins before starting car.

I again forgot to check the reviews before buying. This is getting returned immediately, now that I realized this is a 20 amp charger, not a jump starter even though it is labeled that way. This item uses dewalt batteries to CHARGE another battery, it does not jump start an engine. With the typical dewalt battery this will provide around 5% of charge, which won't even help with starting a car from a very discharged battery. The uses of this are so incredibly limited. Other jump starters have features to allow a jump start when a battery isn't detected, like if your battery has failed. This will not do that. This product will literally only work if your car battery just happens to be on the very edge of having enough charge to turn the engine over, and even then it will only give you enough charge to attempt one start. So if you have a bad battery that won't hold a charge (which you won't know until you shut the car off next) and you used this to luckily start it, don't let the car shut off until you have a new car battery in hand. Ridiculous. Also, which should be obvious, the lights are covered if you use a large Dewalt battery. As a note, since this is just a charger and not a jump starter, this product is just a voltage regulator, taking the 18v Dewalt batteries (20v max) to a regulated 14.4v. This means this product should cost about $20-30 retail, as the electronics are incredibly cheap. They have bloated the price to the level of other jump starters, when it isn't a jump starter.

it just stop working ????

I've got a brand new UTV and it takes an 18 V battery, the starting feature must be a defect because I can use it out on the trails and if I turn it off many times it won't re-start again so until I purchased the DEWALT DXAE20VBB Automotive Battery Booster and paired it with my Dewalt 20 V battery, I don't need to keep it running to make sure I don't have to walk home, My UTV hasn't improved but my life became much easier when I take it along everywhere I go, This booster will start up my UTV in 5 seconds with my Dewalt booster.

It definitely helps

I have had this for some time now and not really impressed. It could be a lot better! But for the price it's ok. It works once u figure it out! It works like a charger! Not a booster! And the batteries are key. As long as your battery is not totally dead it works to top off your weak battery.

When considering this product you need to see what is powering it. The first thing that impressed me was the DeWalt name but it had little to no impact when I connected it to my dead car battery. Fortunately it accommodates charging my phone and other small devices so it wasn't a complete loss. If you want a 12 volt emergency solution for your car I suggest staying with the well known plug in boosters and chargers. signed, "Disappointed"

Excelente

Load of s***. When I want to use it and jump start my vehicle. The jump start wouldn't work.

طلبت المنتج كالعادة و صل لي مغلف بأحسن كرتون وفرحت جداً ... ولكن مع الأسف الشديدجداً. وصل المنتج ناقص بدون بطارية وبدون شاحن .. بعد إنتظار مدة طويلة جداً ما يقارب ١٥ يوماً .. راجعت نفسي أبحث في سوق الأمازون بطارية ومع الأسف ليس له أي عنوان ولذا ... حذر ومنع الشراء هذا السلعة

Sad you couldn’t jump start a moped with this. I’ve actually jump started a car with a dewalt battery and had better results than I did with this.

Sorry but the 20v battery that is exclusively matched to this jump starter is unavailable everywhere, even on the website of the manufacturer.
