Review: A must have! - This power bank got my insulin from Los Angeles to Texas on a 3 day Amtrak trip in the middle of a hot summer safely. I used it with my Voyager insulin cooler/chiller. There was about an hour when the power cut off on the Amtrak, but the temperature held and I was able to see the temperatures from the usb lid throughout the trip. I kept it plugged in throughout the trip - via the cigarette lighter/charging in a car, plugged into the wall outlet on the train, and when not near an outlet the powerbank had plenty of power left. I was worried I might run out of power and lose several insulin pens. But this along with a Voyager was dependable. Now I am confident about future times it may be needed.
Review: a must have if you have the insulin carrier - this backup last a good 48 hours in use, the good thing about the holder it goes with is you can plug it in the car when you're traveling and charge the backup and then use the backup on the plane or train whatever you're traveling on and keep your pens cold.

### ⭐⭐⭐⭐⭐ Easy to Use
*by C***A on May 26, 2024*

Great battery, easy to charge, easy to use. I just wish they lasted longer when powering the 4AllFamily cooler. When fully charged they will go for a few hours, but not long enough for a direct flight from US west coast to Europe. For flights over 7-8 hours, if the seatback USB ports don't work, you'll need two batteries for each 4AllFamily cooler you have.
