KE and Anime Shikai Kenpachi's Physical Might: 4.225006995298E+29 Joules or 100.98 Exatons, so pretty much Moon lvl.
Keep in mind that this is Shikai Kenpachi with the eyepatch on. Without the eyepatch he might be Small Planet lvl, but he's definitely Small Planet lvl at full power without the eyepatch + Bankai.
