Useless gadget ruins automotive charging experience

This product failed to live up to its promises. While it may seem like a convenient tool to have in a garage or shop it actually caused more trouble than its worth. Its faulty design only led to frustrations in charging automotive parts and did nothing to enhance the experience .The one perk of the adjustable feature ultimately could NOT make up for its numerous drawbacks..

Pros
  • adjustable feature
Cons
  • faulty design, useless in automotive charging tasks

Perfect for my use and very cheap.

if you want to add flexible power to any low voltage device, this is it. Powered by USB or Lithium, with charge and boost/step-down circuitry to any reasonable voltage. very cheap and tiny. The only thing that would make it ideal is a higher current.

Pros
  • The default output voltage is about 9V, please debug it before using.
Cons
  • Hard to say
