Wall chargers for phones are not something I generally get excited about but as this handles “Power Delivery” (a new standard for charging) for phones AND has enough power for a Raspberry Pi 4 or modern tablet/notebook, here goes. The RP-PC112 UK version is a white, neat-looking USB-C wall charger weighing 105g and sized at 82.8x52x48.1mm. Equivalents for other countries may vary in size. Here’s an Amazon link.
But I’m writing about this because of size and weight (just getting the specs out of the way). The important bit is that the connector on the front (no USB lead supplied) is USB-C. Power output is 5v or 9v or 12v or 15v or 20v or 20.3v at 3A regardless. There are tester units that can trigger specific voltages but these are currently on long lead times from AliExpress. I desperately need that the tester above but they are talking about June delivery.
If you are familiar with fast chargers you’ll know that they can automatically adapt the output using a special technique depending on what they are charging. So for a simple 5V USB gadget you are looking at 5v at up to 3A whereas for phones able to handle quick-charging, higher voltages are used.
I tested my Pocophone F1, starting at 47% and plugging it into the charger using a handy USB-C to USB-C lead. Let’s see what happened:
SO, first things first – the only USB-C to USB-C lead I have is 1 metre long – normally I would not use a USB lead that long for charging a phone. In this case my Pocophone F1 responded with “Quick Charge” – that’s a good beginning.
Start time at 3:35pm with the phone initially at 47% (the phone on standby, with WIFI connected but apart from taking and processing then uploading a photo of the charger, not in use). By 15:51pm the battery was at 73%, thats 25% charge in 16 minutes, WIFI on, Bluetooth off. At 4:20pm (50 minutes) the phone had reached 92%. With that success, I put my Xiaomi Redme Note 8 Pro on chsrge – this said “charging rapidly”.
Can’t complain – and that’s on a long USB-C lead. For assistance, contact firstname.lastname@example.org
