USB Type-C Specification 2.1 allows up to 240W Extended Power Range (EPR)

USB PD EPR Flow 240W

Many devices have switched from a Micro USB port or a power barrel jack to the USB-C port in recent years, as the latter allows for higher currents, and up to 100W power input in USB PD (Power Delivery) compliant systems. While 100W will be more than enough for most devices, more power-hungry devices or systems still need a power brick, for example, gaming laptops and mobile workstations. But the USB Type-C specification 2.1 aims to change that by upping the maximum power to 240W. As noted by Benson Leung in a Reddit Thread the part of the specification that handles the 240W power is the EPR (“Extended Power Range”) that defines requirements for cables, chargers, and devices: 3.11 Extended Power Range (EPR) Cables 3.11.1 Electrical Requirements Extended Power Range cables have additional requirements to assure that these cables can deliver the full defined voltage and current range for USB […]

BLUETTI EP500 is a power bank & UPS for home appliances (Crowdfunding)

Bluetti EP500

Many people are using a power bank to extend the battery life of their mobile device(s), and there are also laptop power banks which higher capacity and support for 12V and/or 19-20V besides the usual 5V. But BLUETTI EP500 & EP500Pro go up a notch as the systems aim at powering multiple home appliances or be used as UPS in case of power failure, or whenever you need to use tools or appliances away from the mains. BLUETTI EP500 & EP500Pro specifications: Control system based on Texas Instruments C2000 dual-core Arm+DSP real-time microcontroller AC Rated Power EP500 – 2000W (peak 4800W less than 500ms) EP500Pro – 3000W (peak 6000W less than 500ms) Power Input EP500 600W max, 100-264V AC via AC input – Charging time around 9 to 10 hours 1,200W max via PV input or T500 input (55-145V DC, 20A) – Charging time around 5 hours with solar panels […]

PinePower 120W desktop power supply features display, USB PD, QC 3.0 and wireless charging

Desktop Power Supply Qi Wireless Charging

Pine64’s January update includes the launch of PinePhone with Mobian operating system, some limited details about the upcoming Quartz64 RK3566 SBC that will ship with 4 to 8GB RAM, and other news about all their products. There’s not enough details yet to write a post about Quartz64, but another product caught my eyes: PinePower. Yes, Pine64 is now offering power supply, and last month they presented PinePower 65W GaN power adapter that looks similar to MINIX NEO P1 power supply, albeit slightly larger. But I find the desktop version of the power supply even more interesting with an integrated display that shows voltage and current for each port, and also adds Qi wireless charging. PinePower “Desktop” version specifications: Display – Shows individual port voltage and current status USB charging ports 1x USB Type-C PD port up to 65W output with support for 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3.25A 1x QC 3.0 […]

When USB-C to USB-A adapter meets USB PD charger…

USB-C PD charger and USB-C to USB-A adapter

MINIX NEO P1 is a 66W USB-C power supply/charger that can handle up to 3 devices, but I’m already using its big brother NEO P2 (100W) to power single board computers or other compatible devices that I may have to review. So instead, I plugged it in my bedroom’s power extension since it’s so tiny and provides three extra USB ports for charging devices. The problem is that two of those are USB-C ports, and I don’t own any USB-C to USB-C cable, so I went shopping for such cables, but soon realized I could probably “save money” by purchasing USB-C to USB-A adapters for less than one dollar each as I already own several USB-A to USB-C / micro USB cables. I got two of those and inserted them in the tiny USB PD charger. Spacing between the two USB-C ports was wide enough to the adapter fitted just […]

MINIX NEO P1 tiny 66W GaN USB-C power supply can handle up to 3 devices

I’m now using MINIX NEO P2 GaN USB-C charger for all review using USB powered devices. But with four-ports and up to 100W of power, it’s a bit over-powered for one or two Raspberry Pi 4 or equivalent SBCs, and it also costs around $60. So the Hong Kong company has now introduced a new model with MINIX NEO P1 being a tiny 66W GaAN USB-C power adapter with two USB-C ports and one USB Type-A port and international plug adapters that make ideal to use on the go. MINIX NEO P1 key features and specifications: Power Input – 100-240V AC input with 2-prong US plug and adapters for EU, UK, and AU Power Output Up to 66 W in total 2x USB Type-C ports support up to 65 W with USB PD 3.0 (5-15V/3A, 20V/3.25A) 1x USB Type-A port supports up to 36 W with QC 3.0 (5V/3A, 9V/3A, […]

8-MOSFET solid-state power driver works with Raspberry Pi, Arduino, ESP32 and other maker boards (Crowdfunding)

8-MOSFET Raspberry Pi DIN Rail

Using inexpensive relays to switch AC or DC loads work well in most cases, but those relays will be quickly damaged when faced with high DC voltages, fast switching times, or other endurance requirements for which MOSFET’s are better suited, and that’s why MOSFET power supplies are found in 3D printers. Sequent Microsystems has made a habit to provide specialized Raspberry Pi HAT with relays or terminals for resistance temperature detectors that are stackable to supports a larger number for I/O or sensors. The company is now back at it with the 8-MOSFET stackable, DIN-rail mountable board that works not only with Raspberry Pi SBC, but also popular Arduino, ESP32, and other maker boards. 8-MOSFET key features and specifications: Eight MOSFETs with status LEDs 4 optimized for high-current (HC) loads up to 10 A / 24 VDC 4 optimized for high-voltage (HV) loads up to 2 A / 240 VDC […]

Giveaway Week – MINIX NEO P2 100W USB-C Charger

MINIX NEO P2

MINIX NEO P2 is a 100W Turbo 4-Port GaN Charger with two USB-C ports, two USB-A ports with support for USB PD 3.0, and Qualcomm Quick Charge 3.0. I’ve been using for recent reviews of NanoPI R2S & NEO3, as well as Raspberry Pi 400, and I really like it as it saves me a lot of space, I don’t have to worry about undervoltage, and I can power up to four boards from a single power supply. MINIX sent me two samples. I’ll keep one for me, and sent the unopened one to one of CNX Software readers. To enter the draw simply leave a comment with your country and whatever else you’d like to say. If the country is missing, I’ll consider the entry void.
