Ok, i need to comment on this because i literally just threw mine away. I originally bought mine through amazon for around $55, and it lasted about 5 battery charges and died a month past the one year warranty. Customer service was no help and they said these units arent meant to be repaired, only replaced. Amazon couldnt do anything for me, and Stanley refused. I instead spent double the money on a Schumacher charger that already has recharged 2 batteries for me ( only today ) and works much more efficiently. Buyer beware
Agreed, if you want a good Screwdriver or Hammer go with Stanley. Other than that they’ll sell their name to go on anything regardless of the quality.
This thing really works. I have a car that is always put away for the winter. This keeps a trickle charge on it and when I need a jump for extra juice to start it up it will fire up the engine with no problems. Had it for years and has been a Steady Eddy for the garage.
