Not experienced this myself and ive had my MVP for months. I use a Davide Glasso with the beauty ring. I wouldnt fault innokin... Not a single company in the history of ever has had a 100% flawless run of products, a few QC mishaps are bound to happen. Just curious, were you charging it via the *included* cable and adapter? Fairly sure I read somewhere innokin saying to only use the included charging tools. Not sure if it would make any difference, j/w.
Yes I was using the included Innokin approved charger & cord.
