The cable itself seems to be of decent quality. And I love that it comes with an adapter so I can charge my various power stations which mostly use 5.5mm and 8mm DC connectors for charging. For an 8mm DC head, this is very reliable. I used it to charge myjackery 240 and it fits perfectly and charges myjackery with no problems. However, the 5.5mm adapter, complete with cable as a bonus, is complete rubbish. It bent the first time I used it! And it's pretty loose when plugged into my power stations, and I often have to check to make sure it's plugged in at the "right angle" so it can charge the device. To be honest this is the main reason I chose this cable over others so I can charge all my power stations. And for those of you willing to spend time dealing with customer service, AVOID this cable entirely as there is NO CUSTOMER SERVICE! I tried looking for warranty information on the Revain page and there is a link to it, but when I clicked it it just took me back to the product page! There is no customer service but luckily I can still use an 8mm head for my jackety.
