I tried to fully charge my new purchase that I received 80% charged but the device would shut off after a 1% charge. I changed outlets but still could not charge this device more than 0 - 1% before it would shut off. Based on your website's T-shooting advice I plugged it into my phone charger. I had no trouble charging it using my phone charger. Obviously, the charger sent with your device is defective. How can I have a replacement sent to me? 0 Please sign in to leave a comment.
