I am so very pleased with this device. It keeps your devices fully charged while you're on the go. It's heavy, so do consider that as it will add some weight to your travel pouch. I would say it weighs about the same as a 3 pound weight. It's encased in what feels like very durable plastic. I definitely don't think it would survive a drop on concrete, but if you've come across this, you are not the accident prone type anyway. This is a very cool looking, highly functional, properly priced peice or equipment for those that are on the go often and need their devices charged quickly by a high capacity device. This fits the bill perfectly. The battery capacity is through the roof. You can charge an S25 Ultra for 0 to 100 percent approx 3 times. Same with the iPhone 16 pro max. Super fast charging is supported, and you can see how long it will take this device to recharge, and power left. You can also see the charging speed of whatever you plug into it. Small travel pouch is included, along with a high quality braided type C cable. Don't think twice, this is the one to get!
