REVIEW – The last time we travelled, I brought no less than 5 different chargers for various phones, tablets, laptops, and other devices. If only I’d had a single charger capable of charging them all, especially if it could charge several at once! Today I’m reviewing the VOLTME 140W USB C Charger which should be able to do all of that, in a package smaller than the 140 Watt single port Macbook Pro charger.

What is it?

The VOLTME 140W USB C Charger is a GaN AC charger capable of charging up to 3 devices at up to 140 watts total. The handy chart from VOLTME shown below breaks down the different charging options:

The VOLTME 140W USB C Charger supports what I believe are all of the modern USB-C and USB-A charging standards: PD (Power Delivery) 3.1, QC (Quick Charge) 5.0, and PPS (Programmable Power Supply – which modifies the current and voltage in real time according to device’s needs).

What’s in the box?

Design and features

voltme 140 06

The picture above shows the 3 ports and LED light on the face of the VOLTME 140W USB C Charger. If you’re only plugging in a single device, the USB-C port at the “top” will provide up to 140 watts, the second port up to 100 watts, and the USB-A port up to 22.5 watts. See the chart earlier in the review for different combinations and what power will be supplied to each port. Unlike other multiport chargers I’ve tried, I can be confident that any combination of USB-C connections to various laptops will work on all at reasonable power delivery levels (some of my multiport chargers cut some ports to a trickle when multiple devices are plugged in).

On the backside of the device, the prongs can be folded in for transport, making for a quite compact travel charger option that you can throw in a bag. There are smaller PD charger bricks out there, but usually they’re single or double port affairs at lower wattage levels.

Finally, details are printed on one side if you want to review all the specs.


Setup is as simple as plugging in the VOLTME 140W USB C Charger into any US 120 volt wall outlet. The small white LED logo on the front lights up when you have power, and you’re good to go. Oh, and I guess you’ll need to add your own USB cables – up to two USB-C and one USB-A, none are included with the charger itself.

The VOLTME 140W USB C Charger delivers exactly what it promises: up to 140 watts to a single device, or that full amount distributed to multiple devices.

I tested with an older Macbook Pro, a Samsung S8+ tablet, and a gaming laptop, and verified with my voltage tester that I was getting 65/45/22 watts across the three devices. When plugged into a single laptop under full load, the full 140 watts were delivered with no drops or cutouts (I even gamed on this for a while instead of the 220W wall charger the laptop came with, and only saw small throttling moments and slight battery drain when really pushing it hard – it would take a full day of hard gaming to drain this particular laptop when connected to the VOLTME 140W USB C Charger. For most people it’s probably a Goldilocks charger: small enough to be easily portable while more than meeting your on-the-go power needs for pretty much any device.

What I like

  • Reliable
  • Cheaper than the Apple 140W charger with more ports
  • Supports pretty much any modern USB device

What I’d change

  • I wish at least one 140 W USB-C cable was included: I’m not sure which of my existing cables is rated for that wattage

Final thoughts

The VOLTME 140W USB C Charger is already a welcome addition to my daily workflow as I move from room to room, and will be invaluable on the next trip, when I can take just this one small charger and be confident it can handle my phone/tablet/laptop with ease. Just remember to also stock up on whatever USB cables you’ll need, because this device assumes you already have them.

Price: $139.99 ($99.99 at time of review)

  2. This looks very convenient! The only problem I’ve ever had with this style is when using it on an airplane. The weight of the charger causes it to fall out of the loose-fitting seatback outlet so I’m trying to find a solution to keep it in place. Otherwise, I love the efficiency of one charger for everything.

    1. Totally agree, I hadn’t even thought about that but it’s been a problem for me in the past too. For what it’s worth, I have a loose plug in my home, and this charger stays snug in it, pretty good prongs. 🙂

  3. The other charger this site reviewed a bit ago, was a true travel charger (e.g. it could work overseas), the LULULOOK 100W USB C Charger. Comes with adapters to use in countries other than those in North America. If this adapter would come with those I’d probably look at buying, but w/o that I will just buy another one of the LULULOOK 100W USB C Chargers.

    1. Those adapters are a couple bucks. I think I bought 4 European adapters for $10 a couple years ago (and since European plugs are ‘innies’, there wasn’t the external adapter depth to add to whatever you plug into that. I recently got a 65W charger with 3 USB outlets and now I just travel with that, a European adapter, and iPhone-, Apple Watch-, and Mac-cables. Sure, 65W doesn’t charge my MBP at full rate, but who cares when traveling? In return you get a pretty tiny charger that doesn’t fall out of loose sockets as easily.

      This article is missing a size comparison photo so people can get a better idea about how big it is.
