How much power does it provide to charge a connected 15" MacBook Pro (2016)?

I have a 15" MacBook Pro (2016) with 4 thunderbolt 3 ports. Instead of using a dock and raid combination, I am considering using this Raid storage - as it comes with a convenient DisplayPort on the back. Would this be able to provide full charging for the laptop? How much charge would it be able to provide the laptop? I think the 15" MacBook Pro charges at 80W. I use capture one pro which is quite power hungry!

Thanks for your response. Cheers. Ankur

  • Let's start with the assumption your asking about Thunderbolt 3 and not USB 3.1. Fair, good, lets progress. For any manufacture to make a charger or port to Thunderbolt 3 or whatever number standard, they must build to Intel's standard and submit working production samples that are representative of what they intend to sell. Once Intel give the product their blessing after testing for voltage and amperage acuity the manufacture can go ahead with production and sales. Thunderbolt 3 standard states USB power delivery over TB3 at a maximum of 100 watts of power over copper cables within the USB TB3. Intel provides three controllers that they designed, 1:DP Double Port PCIe 3.0x4 two TB3 ports DSL 6540, 2: SP Single Port, PCIe 3.0x4 one TB3 port DSL 6340, and lastly 3: LP, Low Power PCIe TB3 3.0x2 one TB3 DSL JHL 6240.

    The higher end devices, like yours, MBP used Double Port which virtually guarantees ANY Thunderbolt 3 device connected to your laptop will not only allow you to transfer data at 40 Gbps, transmit 4k display images, stream audio and charge your laptop simultaneously. Just remember to keep the TB3 cable to 1.5 meters or less for optimal results. The longer the cable, the more signal drop out, or just sluggish results. Also invest in a decent TB3 cable. Don't go and spend a hundred dollars, but buy one from a known brand with good reviews and preferably gold plated end, and oxygen free copper wire. This will help with the signal continuity and help prevent the cable from breaking down over time. The thin white cables are good to give away or keep as a back-up in the bottom drawer.

    Thunderbolt 3: 40Gbps 100 watts of power backwards compatible for USB 3.1 at 10 Gbps and four lane PCIe Express Gen 3. Intel finally made something on time and cheap enough for everyone. Starting in Q3 2018 TB3 goes off patent and is OPEN TO EVERYONE FREE!

    Well Ankur, I hope you enjoyed my little response to your question about Thunderbolt 3. If it says TB3,it does it all.
