Review (5/5): Well-built, hoping it lasts the test of time
worked on one round trip of 500 miles to keep my phone charged. Kept it at 100% charging rapidly the whole time over a usb-c cable. The fuse did not blow out, which is most important to me -- that this product lasts. The fan jolted me the first time I heard it but it works great and turns off after a short time.
