★★★★★
Best portable I have bought in years. Used it for two weeks straight to charge a phone and watch. Also dropped it from a pretty decent height on accident and it didn’t even leave a dent or scratch. It is fairly large but it fits great in a backpack or cargo pocket. Definitely worth the price.
Very durable and long lasting
