Died after less than 10 uses

There seems to be an ongoing problem with these little transformerless 'smart' chargers dying almost regardless of brand. Just check the 1-star ratings for all charger death reports. This device worked great for the first half dozen uses until I tried charging the battery a few weeks ago. The battery was out of the car and in the garage and I checked the charger before I went to bed and it was warm and still charging. In the morning I went to the garage to check the status of the charger and it

Pros
  • GOLS certified
Cons
  • Something else

I recently bought a used 2015 Subaru Outback Limited based on all the reviews I have read and carefully researched. However, it has been ten years since I last bought a new car. My Ford Taurus SEL station wagon had almost 200,000 miles on it and I really didn't want to change it, but that's another story. I quickly realized that these new cars are meant to be driven EVERY day and I'm not that much of a driver (in retirement I don't have to drive 100 miles a day to work). With today's…

Pros
  • Satisfied so far
Cons
  • I vaguely remember

FIRE HAZARD! in jump starters, chargers and portable power packs

Tender Battery 12V 5A DO NOT USE THIS PRODUCT IF LEFT UNATTENDED, FIRE COULD RESULT Car battery. The Battery Tender was solid orange-red when I last looked after about 20 minutes of charging. I took a nap and came back a few hours later to find the green box was blinking to indicate the battery was fully charged but felt very hot. I immediately removed the battery. When I next tried to charge the battery it was just blinking orange/red which means the battery was not powering my battery. The…

Pros
  • cool product
Cons
  • nothing

I bought this to charge my AGM car battery because I like bass (I didn't realize I had enough bass until my wife called it childish - yeah, me that guy ). Using my amplifier at high volume can drain the battery and overload the generator. I bought this particular make/model after doing my homework. This thing is PERFECT (a term I don't use casually) for a charger. First of all, the packaging is amazing - almost over the top! How often do you see that these days? Practical heavy tin box for…

Pros
  • Certified
Cons
  • Cord is shorter than other picks
