I bought the his to replace a similar- appearing light I had lost. But what a difference. Yours has a USB cable so I could fully charge it in a couple of hours. The other one had to sit in the sun for much longer on a sunny day, and forever on a cloudy day. And this charge holds for seven years? (Of course I don’t expect to test that claim.)I will use both on my boat and in my car (or get a second one). A truly superior product
