Dewalt 20V 3 In 1 Professional Battery Booster | USB Power Station, Powered by DeWalt 20V MAX and FLEXVOLT 20V

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

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.

Used almost straight away on my mondeo where battery died due to the lack of use, within 5 minutes of being on using a 4Ah battery the car started first time.

it just stop working ????

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

great compact product that works as advertised using standard Dewalt battery.

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.

This charger /jumper has been amazing. I think most of the bad reviews may be from people that are using 5 amp batteries or less. Use this with a flexvolt 6 amp or 9 amp and it works amazing. Like most people have commented, this won't jump a completely dead and worn down battery, due to the safety circuitry inside.
