I can confirm that the Modular Power Armor can be charged directly with IC2 power (Tekkit Lite 0.6.5). I have charged my Power Tool in both a BatBox and an MFSU - strangely, the power drain is instant! I fully drained my MFSU a split second after I plonked the robot arm in the charging slot. Seems like 2EU = 1MJ, feel free to correct me on this.

Also, all your chargeable equipment will recharge if you stand on top of an Universal Charger block (a part of the Energy Bridge mod). After stepping on the charger, the charging will continue even if you walk 2-3 blocks away from it.
