Review: Works amazing for fairy lights and decorations - I’ve spent years going through batteries for fairy lights for the holidays. I spent a lot of money on lithium rechargeable batteries which need up being a bust as they die quickly. These solved my problem! I can put them in any decorations I have that take batteries. Great value. Easy to install. The cord is super long. Note they should ONLY be used indoors, and probably monitor the first couple days to make sure it doesn’t result in any electrical issues. But otherwise, looking forward to using these in all my decor!
Review: Works great! - Used this with a portable bubble machine and it worked great! We were able to use the machine for a few hours until we ran out of the gallon of bubble solution. Made it super easy to leave plugged in and not need a ton of batteries during a party.
