## Customer Reviews

### ⭐⭐⭐⭐⭐ Small and portable
*by J***A on April 9, 2025*

The media could not be loaded. I like this since I can see how much power is being used from my backup batteries as I’m using them. Very small and very portable. It toggles between watts and volts

### ⭐⭐⭐⭐⭐ A better Power Meter, Accurate, Full USB4, Volt and Power display
*by S***S on June 13, 2024*

The media could not be loaded. USB C is a very complex form factor and is most confusing connector of all. So is the power delivery through USB C, literally like in Power delivery as in PD (which actually stands for a defined standard) and or QC, PPS or just 5v etc. Attempt to unify the power supplies so that same power supply can be used for every device from a Bluetooth headset to a laptop ranging from 5v/1w to 48v/240w it has become quite complex. Every thing in the charging or power path plays a role including the most mundane cable. Every component talk to each other.This power meter is something that you can put between a power supply or hub and the cable connecting to the device. I helps you read the actual power consumption in real time together with voltage. This unit pleasantly surprised me and this is why:> Small dongle size that you can use with any cable, important with some devices that need special cable.> Power meter: It reads both volt and wattage in real time and the readings are quite accurate for this type of device. It read voltage from 2.8v onward. I tested it from 2.8 -to 28v and up to 100w delivery without any heating. It read in either direction, you can put it at supply or device end. It doesn't display what power level the device negotiated but the real time consumption. Voltage tells you whether a 15watts is 5vx3A or 15vx1A. It helps you determine the issues or limitations of the chargers/power supply etc.> Data line: Most power meter cables support only USB2 connections. This cable supports a complete USB4 data lines, that means you can use it with any USB4/ Thunderbolt hub, specially the powered one. More importantly being and extension type dongle it must and does have both sides of D+ D- lines connected. This is a common problem with many USB4 extension cables.> Internal Resistance / Shunt: Being a small dongle you won't expect much internal resistance. However, power meters have a shunt resister which is common design practice for current measurement. Measuring the IR gave me about 10 mohms on the VBUS and 30 mOhms on the ground, that tells me they used the shunt on ground line. It may be a better choice because most cable struggle with VBUS IR. THese IR values will add to your cable IR.You must keep in mind while using this with a high current device that your actual cable is a good quality otherwise the voltage drop might creates problem for some sensitive devices. OnePlus phones which uses higher current than the PD limit of 5A, limited the charging current slightly lower with this in series, but still connected WARP charging.> E-Marker: Being an extension type dongle this should not have an E-Marker and it does not. This allows your actual cable E-Marker to control the current that it supports.> Display is quite dim, but I personally like it because I do not like blazing displays on these devices it becomes a distraction.Overall this is one of the better USB power meter that you can use with any cable with full USB4 data line (no missing one side D+ D-) and voltage display. It is reasonably priced.

### ⭐⭐⭐⭐ extra geek points
*by C***S on June 20, 2024*

Adds fun to daily boring charge routine. I wanted a way to create visibility on how much power is flowing through my charge sessions and also to verify the power in/out from my charger. Having these added to my existing charge cords is an extra geek points. So far, it has been accurate is measuring watts flowing. it even provides the voltage reading. build quality is good as well. The display is a little bit on the dim side, and wish it was brighter.
