Anyone using this combination in the field for external battery source? Worked great for years thru several generations of laptops--until I (somehow?) lost the cable interface. Energizer no longer supports (lousy even when they did) and won't even admit to having made it. Apple says 'too risky' and won't even discus the required cable. EBAY has several XP18000 units but still leaves me without the MAC interface cable. I have learned (the hard way $$$) the XP18000 cannot be connected to the USB port. Any suggestions on finding required cable?
Or any suggestions for a more current external battery source alternative. Not important but am shooting 7DM2 and 5DM4...

I'm not familiar with that Energizer, but I swear by this one:

3.5 pound, brick-size, 120 volt, 120 watt inverter with lithium battery. Use your existing AC power adapter.

Buff also sells a larger 400 watt unit (six pounds) if you want more juice.
