ITAWEY Fast Power Adapter 18W, USB, Universally Compatible Phone Charger, Quick Charging QC 3.0

The charger arrived quickly and charges my phone at a good speed. Like the fact that it’s easy to connect one handed using the magnetic tip. Recommended.

Doesn't work on any phones that I try

Very quick delivery and works great when needed and very effective

Item was ordered and arrived the following day. It was well packaged and contain all the necessary stated accessories. The fast charger feels very light but is a good build quality. The magnetic charging cable has a very durable coating which seems to prevent back coiling that is typical with nylon coated type cables. This should reduce the potential for internal breakages. The fact that the manufacture testing for the cable included this factor is also reassuring. The USB C connector has an LED that indicates power on and this is also useful in the dark but not overly bright. The aluminium USB C connector is strongly magnetized and easily connects to the charging cable with minimal effort. I ran my phone down to 1% and then charged it through to 100%. My phone battery has as 3000 mAh capacity. I used a battery analyser to view progress. My main concern was about overvoltage, overcharging, overheating. I purchased this product due to the safety features detailed in the item listing. I was reassured by the CE and and RoHS certification. Initially the battery temperature increased slightly but this is to be expected. Once at a stabilised temperature, the current flow increased considerably, as did the voltage but neither were above acceptable limits. The rate of charging as a percentage increase was much greater up to a battery capacity of 65% and then dipped slightly. I understand this is normal for lithium ion batteries, as this is the constant current phase. Even so, the charging rate was still very good above 65%. Overall, the temperature increased from 37°C from a starting point of 31°C. This is well within acceptable limits. The current and voltage levels were also within acceptable limits throughout. There is a high pitched buzz audible but then I do have very sensitive hearing. This is normal and not a cause for concern. In conclusion, it took 70 minutes to fully charge the battery, the charger and phone not get overly warm and the magnetic cable was very convenient to use especially in the dark.
