    Will this charge a Nintendo Switch via USB-C? What about a Dell XPX 16 9560?
    A shopper on May 31, 2017
    BEST ANSWER: Thank you for your question. As long as your two devices will support a 2.4A charge then you would have no issues using this power bank to charge your devices.

    Decent start in the USB-C transition
    This is a decent accessory to go along with my Microsoft Lumia 950, which has its own 3,000mAh battery. So I needed something big like this to keep up. Someone who reviewed the white version of this power bank warned others that the provided cable does not meet specification, so I was slightly weary about this happening with this black version. Luckily I stocked up on correctly spec'd USB-C cables beforehand. I just wish Benson Leung of Google himself did a review on this with his technical expertise to advise others. Anyway, still good pack to have for one night away from grid power.

    PROS: Great capacity and USB A and USB C outputs with decent Amp ratings. Can charge my Lumia 950 and another device simultaneously.

    CONS: Provided USB A to USB C cable is too short and doesn't charge the power bank.
    Miss the little LED flashlight like the other 1A/2A chargers have

    10000mAh USB-C 15121 Has Systemic Charging Issues
    Like others have noted, the USB-C 10000mAh battery I recently received will not charge with the included cable, except in my case I cannot get it to charge at all with several different cables, various plugs (including 2A+), or direct to a computer, all of which have no problems charging my USB-C phone. I sent a request to the technical support department and received no response after several business days. I also cannot find a manual anywhere, the card that comes in the box says to just search the website for 15121 to find the manual, which only takes you to the product page here...

    PROS: The 50% charge it came with worked well, so I guess that gets it one plus.

    CONS: Included cable is inadequately short, it's just shy of 10 inches, the relatively standard 1.5ft would be nice, or at least 12+ inches. As others have noted it probably won't help you charge the battery either.

    Very reasonable budget USB-C power bank
    Good build quality, high amperage USB A and C ports, if you HAVE AN EXISTING USB-C CHARGER AND A SPARE USB C CORD it's a great buy. Did not test included USB C cord for compliance, as other reviews have mentioned it's not up to spec, but it's too short to be useful anyway.

    Great Bank for your Buck
    I've been looking for a USB-C bank for my Nexus 5X for quite some time. This 10k mAh USB-C bank suits my needs perfectly. I use my phone to play music over a bluetooth speaker at work, and without the charger, I'm at 20% by lunch time. The bank gets me through the rest of the day (back up to 100% on the phone by quitting time) with roughly 25% juice to spare in the bank itself. The size is great, it fits the cargo pocket of my Dickies that I wear to work, it's just a tad too big for regular pockets, but it doesn't take up too much room in a backpack, lunchbox, or whatever else you might stash it in. The cord it comes with is very short, so if you need something longer than 6 inches keep that in mind. I picked up a 1' braided cable from Amazon for less than $10. I gave this product 5 stars because it suits my needs well, but it might perform even better for others who aren't using it in a hot warehouse every weekday over the summer.

    Select Series Power Bank
    The device was chosen for 2.4A and multiple charging capability.
    It is a little big for pocket but worth the hassle as it works well and is FAST. Be aware that the connector is USB-C and you will need an adapter to facilitate USB-A/B use - use a baggy or similar to keep everything together. Otherwise, great product.

    Works great!
    So far this is great! A bit bigger than I would have thought, and it only fills up via the USB-C cable, but it holds a ton of charge which is nice.

    Good Product but...
    Product works but the cord is much too short.. Needs to be at least 2 feet long.

    PROS: Works very well

    CONS: The cord needs to be longer.

    Works Very Well. . . Few Quirks
    Hey it's a portable battery pack. It actually works well. On the USB-C port it charges a phone as quickly as a USB-C rapid charger. ALso it charges back up quickly when on a comparible charger.

    The capacity of the battery seems pretty small. I can fully charge my phone (nexus 5x) 1 time but it uses all the bars except 1.

    Still, it does exactly what it should.

    Can't recharge unit.
    I was never able to charge it and monoprice didn't know how either after two batteries, disappointed. I tried to future proof myself with the usb-c but it didn't do what it was supposed to.
