To change the default surge value, select the first option (>32.0V OVP) in the system configuration interface; short press the key to decrease 0.1V; quick 2 press the key to increase 0.1V. Low Voltage Protection Function The default value of the low voltage warning system is 0.00V. To change the default low voltage value, select the second option (8.00A OCP) in the system configuration interface; short press the key to decrease 0.1A; fast 2 press the key to increase 0.1A. Tips: 1. When this USB tester connects to the USB-C device and USB-A to USB-C cable, you need to insert the OTG adapter (Micro USB adapter) into the USB tester to activate the PD charging function. Then the USB tester can be used normally. 2. If there is current in the tester without connecting the load, press and hold the USB tester key, then connect it to the device and calibrate to zero. During calibration, the output should not have any current draw. IMPORTANT: The product is constantly updated and new content is added, so sometimes the version you receive may be different from the description, but it does not affect the quality and use of the product.

Comes with Micro-USB adaptor. *by on Reviewed in the United Kingdom 16 October 2022* I did pay for this myself and it isn’t part of the Amazon Vine Program.I do have one of these under another brand but needed a 2nd one and this looked the best value at the time. These do seem to be generic, with some having a brand name on them and others don’t.As I test a lot of charger and cables, these are really great for seeing what is happening vs. the spec. Where this differs from similar products is that you can go from USB-A to USB-C and visa versa. I have another design that, if you plug one end into a USB-A port, then the other end must also be plugged into a USB-A port as well. Personally, I find that too restricting.You can change the display arrangements but some are tricky to read due to the amount of info it’s displaying, that is unless you’re up close. I tend to focus predominantly on a setting which shows me Volts, Amps and Watts at that time and ongoing.It is easy to use and the display is clear, if a bit small sometimes. You even get a Micro-USB adapter included and a simple plastic storage case. Pricing on this specific design does tend to fluctuate quite a lot depending on the brand, I paid £16.74 for this one, but have seen these (not this specific one) for £25 upwards. For the price, I thinks it is decent value and highly portable.I did run a comparison test compared to the other one I had, they are exactly the same device, and the readings were the same on both.I hope you found this review & photos interesting, informative, and useful. Thanks for reading. ### ⭐⭐⭐⭐⭐ Perfect little tester, but has a small screen *by on Reviewed in the United Kingdom 20 May 2026* For the price, this is a fantastic piece of kit. It shows all the information you could ever need, and even plots graphs of load over time. I used it to check whether a lithium battery charger was pulling excessive current (and hence overcharging the batteries) when plugged into a higher powered USB C port versus a lower one (it wasn't, so it was fine). It will come in useful for other things I am sure. You do need good eyesight to read the screen which is only a couple of cm across. ### ⭐⭐⭐⭐ Works, and duration useful! *by on Reviewed in the United Kingdom 3 September 2025* It lacks a USB C socket for input, so was useless with a USB C, plug-ended lead, like a USB C PSU with permanent cable, like for Raspberry PI, or when it is not practical to directly plugged in to a USB C power socket, because it's the wrong place or otherwise impractical. It seem that I will need to find/make a USB-C socket to USB-C socket adaptor, with PD support, for such situations, which was annoying, so I dropped 1 star!Update 2025-12-02Correction: I discovered that the confusingly labelled "Type-C OUTPUT" can be used as a power input (e.g. a charger) and "Type-C INPUT" can be use as the power output (e.g. a mobile), so the suggested need for adapters was incorrect.The recorded duration was useful to see how long a device took to charge. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/415138174-usb-c-tester-usb-power-meter-2-in-1-digital](https://www.desertcart.no/products/415138174-usb-c-tester-usb-power-meter-2-in-1-digital) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-28*
