The manufacturer Voltme sent me a charger a few days ago, the one with the name Voltme Revo 140 gives an idea of how many watts of power it offers - right! 140 watts. But the Revo 140 has another special feature: it can use devices with the new USB Power Delivery PPS Standard load.

Unfortunately, the scope of delivery does not include a charging cable that supports the 140 watt USB PD. Since Voltme also does not offer a cable for this power, I would currently This 1,8 meter long USB-C charging cable from Anker . Recommend
Design and workmanship
The Voltme Revo 140 is available in black and white and comes with the form factor that we already know from numerous other devices: rectangular and with a built-in Euro plug with which you can plug the device directly into the wall socket.
Due to the light honeycomb structure, which can be found on both side surfaces, the charger looks much more elegant than many other plug-in power supplies.
The workmanship is very solid and robust. So there is nothing to complain about in terms of the quality of the case.
What performance do the connections offer?
The Revo 140 has three USB outputs - two USB-C and one USB-A output. And as is more common with multi-port USB chargers, not all deliver the same power output. To give you a small overview, here is a list of what each port can deliver:
- USB C 1 - Power Delivery 140W - 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/5A, 28V/5A
- USB C 2 - Power Delivery 100W - 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/5A
- USB A - Quick Charge and Super Charge - 4,5A/5V, 5V/4,5A, 9V/2A, 12V/1,5A
You can already see that only 140 watts come out of the first port. And there is another limitation that is usually also present in all multiport chargers: You only get the maximum power if only one port of the charger is occupied. As soon as you plug in several devices, the performance is throttled on all ports.
The ports deliver this performance with different assignments
Since it can quickly become confusing as to which port delivers how many watts for which device's occupancy, I have a table here that shows you what it looks like. Each line basically represents a possible occupancy of the three ports and the watt numbers show the maximum output power that can be expected at the port.
| USB-C 1 | USB-C 2 | USB-A |
|---|---|---|
| 140 W | ||
| 100 W | ||
| 22,5 W | ||
| 65 W | 65 W | |
| 100 W | 22,5 W | |
| 100 W | 22,5 W | |
| 65 W | 45 W | 22,5 W |
If there is no value in a table cell, this means that the port must not be occupied in this combination.
Is 65 watts enough for a MacBook Pro?
If you look at the performance data of 45 and 65 watts on the USB-C ports, if the appropriate assignment is available, then you might wonder whether this performance is enough to charge a MacBook Pro.
I have my Macbook Pro Max M1 (13 inches) discharged below 50% for a test and then connected to the original 100 watt Apple charger. Just to see what the device demands in terms of power when connected to a charger that will definitely deliver the maximum power when it's called for.
The result is pleasing, because most of the time the MacBook Pro only used 50 to 60 watts - sometimes even less. The power display only jumped to values of around 65 to 70 watts for a few seconds.
My conclusion: The Voltme Revo 140 will most likely charge your MacBook Pro just as fast as the Apple power supply, even when fully loaded.
You only have to keep in mind that a 16-inch MacBook Pro (model from 2021 with M1 chip) will probably demand more power - it is not for nothing that Apple recommends the 140 watt power supply units for these models in order to achieve maximum charging speed:
The 140W USB-C Power Adapter enables fast, efficient charging at home, in the office or on the go. It is compatible with many USB‑C charging cables. Apple recommends that you use this adapter with your 16″ MacBook Pro (2021) and a USB-C on MagSafe Use 3 cables to take advantage of fast charging, which allows you to charge from 30% to 0% in about 50 minutes. (Source: Apple)
And that's exactly what the Voltme Revo 140 charging adapter can do - but it can be used more flexibly because you can charge three devices at the same time if necessary.
USB Power Delivery PPS simply explained
As you have already read in the description above, the charger supports the USB Power Delivery Standard PPS extension. The USB PD PPS (Programmable Power Supply) standard was introduced in 2017 by the USB Implementers Forum (USB-IF) as an extension of the USB PD 3.0 standard.
PPS enables fine-tuned adjustment of voltage and current in real time, depending on the device's state of charge. The voltage can be varied between 3V and 21V in increments of 0,02V.
This technology makes charging more efficient and generates less heat, extending battery life.
PPS and USB PD 3.0 protocols work seamlessly together, allowing non-standard currents and voltages to be renegotiated between the charger and the device being charged.
More expensive because of PPS and 140 watts
I read some customer reviews about the charger and some criticized that the Voltme Revo 140 is more expensive than other multiport chargers. Unfortunately, people have overlooked two points that make up the Revo 140's price tag:
- The charger supports the USB PD PPS standard, which can charge compatible devices in an optimized way.
- The Revo 140 supports a maximum charging power of 140 watts. Other chargers only offer between 60 and 100 watts here.
If you look for real comparison devices that support both PPS and 140 watts, you end up with prices between 75 and 100 euros.
My experience with the Voltme Revo 140
I couldn't really push the Voltme Revo 140 to the limit. I don't have a MacBook Pro that asks for 140 watts, nor do I have a device that supports the USB PD PPS standard so I could check the dynamic charge voltage.
What I tried is a comparison when charging my MacBook Pro between the Voltme Revo 140 and the original Apple charger with 100 Watt USB Power Delivery.
There were no differences whatsoever and even when I connected my small 12-inch MacBook to the second port for charging, the Voltme Revo 140 still had more power capacity than the larger MBP required.
Who is the Voltme Revo 140 worth for?
As mentioned above, the Voltme Revo 140 charger is a tad more expensive than similar chargers due to the PPS standard. Therefore, the question arises as to who is worth spending this additional charge of 10 or 20 euros on.
I would describe myself as tech-savvy and interested, but I still don't have a device that uses the PPS charging standard. Neither the iPhone 14 Pro Max nor my MacBook Pro Max M1 supports this standard and thus does not benefit from optimized loading.
However, if you own a current MacBook Pro M2 or will buy a new MacBook, iPhone or iPad in the next few years, you can assume that these devices will be compatible with the USB PD PPS standard.
Since the PPS standard is also easy on the battery due to the lower heat generation during charging, investing in such PPS chargers is particularly worthwhile if you use them to charge expensive devices such as a MacBook Pro, iPad or iPhone. An extension of the battery health can only be an advantage here.
My conclusion on the Voltme Revo 140
I admit, I first had to read up on what the USB PD PPS standard is. Although it's been around for a few years, I haven't come across a charger or power bank that supports this standard.
However, I think that USB PD PPS will play a bigger role in the future, since Apple is now including this technology in current MacBook Pro models. From my point of view, this suggests that I pay attention to the PPS support when buying such chargers.
Whether you should buy the Voltme Revo 140 depends on what your own equipment looks like and how future-oriented you want to buy.
From a technical point of view and in terms of processing, there is nothing wrong with the Voltme Revo 140 and there is also a good price-performance ratio here.
