I have a New Trent NT120R PowerPak Xtreme 5V@2A-1A Dual USB Charger (12000mAh). Can I use this external battery to recharge my 2015 MacBook? I have the necessary Apple brand USB-A to USB C adapter.
iBook, Mac OS X (10.7.5), iBook Author 2.0
I got the ANKER USB-C 20100 and the Macbook 12" 1.3 Ghz . It won't charge the laptop while using it, but it will keep it at the same level of charge for quite a few hours.
It does it's work if the MacBook is closed. But not very fast 😟 which is obvious based on technical specs
No, it cannot be used to power a Macbook. It's for Smartphones and tablets.
Hmmm.... you are the first person to tell me that I cannot. I have read a few 2015 MacBook reviews and the reviewers recharged their MacBooks with the same USB Batteries as they used to recharge their iPads. I was hoping for the definitive word from Apple before I even try using my USB Battery, as I don't want to mess-up my new MacBook.

You're not talking to Apple here, just other users like yourself.
The Macbook requires 29 watts at 5 volts. that battery pack supplies 10 watts at 5 volts, hardly enough for the job.
Ok.... So the MacBook 2015 can be recharged with external USB Battery but the specs on mine maybe too weak? What watts/volts/amps would be necessary for recharging a MacBook?
29 watts at 5v (5,5 amps)
A simpler way to look at it. A little battery is not going to charge a larger battery. Most of the inside of the Macbook Retina is filled with batteries. A battery pack the size of an iPhone is not going to be able to charge a laptop's larger battery.
For the same reason, 2 six volt lantern batteries are not going to recharge your car battery.
Lanny... I understand your battery size example. My USB battery is about 3 times the size of an iphone. Lastly..... will it damage my 2015 MacBook to experiment with recharging my MacBook with my USB battery? Maybe it only has the capacity to recharge my MacBook to a 50% level but on the new MacBook that could be 4 hours of additional use.

No, it shouldn't, the ports are designed to handle voltage in both directions. Trying it may be the only answer to the issue, as I'm sure virtually no one has tried it.
No, it will cause no harm (to the MacBook at least), but it will exhaust the battery pack pretty quick, and reaching a 50% charge is not going to happen, maybe a 30% charge if you switch the Macbook off while charging, half that if you don't.
10-4..... Not sure if I want to be the guinea pig for battery testing but maybe someone else will. Here is one of those reviews that mentioned using existing battery packs: http://bgr.com/2015/04/16/retina-macbook-usb-c-external-battery-pack/
According to Apple: https://support.apple.com/en-us/HT204360
…
Using third-Party USB-C power adapters
Your MacBook will charge from USB-C power adapters not manufactured by Apple if they adhere to the USB Power Delivery specification.
…
It doesn't appear Trent claims adherence to the "USB Power Delivery specification" ("PD") for the NT120R. That doesn't necessarily mean it can't charge a MacBook, but Apple probably won't claim that it should or could work unless Trent builds a USB-PD-spec-conforming battery/charger.
According to Anandtech: http://www.anandtech.com/show/9136/the-2015-macbook-review/6
"Apple’s included [MacBook] 29W charger can deliver 2A @ 14.5V for devices that comply with the USB power delivery specification, and 2.4A @ 5.2V for older USB battery charging devices (phones, tablets, etc)."
Trying to charge a MacBook with something (not USB-PD compliant) that only provides 5V (regardless of current?) may not work at all or work only slowly? Again, Apple only claims support for chargers that, "...adhere to the USB Power Delivery specification."
If anyone finds a external USB battery that meets USB Power Delivery specification, I would like to know the model and brand.
