SKA100 Power Bank Supports 220/110V AC, 12V, and USB PD 3.0 / QC Outputs

SKA100 portable 100W power bank

Power banks are normally comprised of a battery that you can charge from the mains, and then delivers power over USB when you connect it to your smartphone, tablet or camera while on the go. Some devices like laptops, TVs, or fans are usually powered directly by the mains, or a power brick connected to the mains, and if you’d like to charge your devices on the go, you could do so with a portable AC power station. Those are often fairly bulky, but recently I’ve seen Arun showcase an AC 100 watt portable power station at IFA 2019 that looks fairly compact. It’s not available yet through, and there are few technical details. There are however several such power banks on Aliexpress including Sungzu SKA100 power bank that offers DC outputs and one 220V/110V AC output delivering up to 100 watts. SKA100 power bank specifications: Input Voltage Range – 15-30V DC up to 3A via power adapter or solar …

MDP-XP is A Modular DC Power Supply Kit For Your Next Project

MDP-XP Smart Digital Power Supply Kit

My love for modular power supply design can not be denied. I find it cool, how you can increase the functionality of relative less powerful device just by adding another device on top or connected to it. With the explosion of the Arduino shields, the Raspberry Pi HaTs, I must say hardware modular design will surely be here for a long time. An interesting modular product discovered on SeeedStudio is the MDP-XP Smart Digital Power Supply Kit. This product is a new product carried by Seeedstudio as it can be seen on the front page, and it is an interesting product indeed. The MDP-XP known as Mini Digital Power System is a system of programmable linear DC power supply inheriting the modular design concept where you can enhance the basic functionality of the device. It is a cost-effective DC power supply, featuring indicators, stability, reliability and distinct user interface comparable with professional power supplies Its modular design allows it to …

Programmable USB Hub Power Adjustable with Built-In Dev Board (Crowdfunding)

Capable Robot Components has launched its Crowd Supply campaign for the Programmable USB Hub in June of 2019. The hub is a feature rich and component rich USB hub that has a dev board built-in. The entire system is housed in an extruded aluminum case, with all the numbering and lettering and port attachments in brilliant white.  Control power and data flow, directly through the unit. The first 40 units are sold out. There seem to be good reasons why these USB Hubs sell out fast.  There was an in-depth article written on a similar hub some time ago.  Inside the enclosure is an array of functionality packed neatly onto a small board. There are 4x USB 2.0 ports that are High-Speed downstream ports and 1x upstream port, a 5th endpoint on the USB hub exposes 2 12C buses via Sparkfun Qwiic connectors, the UART and 2X GPIO. The input power is delivered to the unit by a locking Molex connector. Also, …

Vivo 120W Super FlashCharge Tops a 4,000 mAh battery in 13 minutes

Vivo 120W

Recently, the news of Vivo 120W Super FlashCharger which can power a 4,000 mAh battery in 13 minutes is on everyone’s lips. It sounds unreal, but it is. While it is not the first supercharge tech, it is one of its kind. According to reports it would be the world’s fastest charging tech for smartphones.  Although no further details were revealed about the Super FlashCharge 120W technology. A Vivo product manager released a video on the Chinese social media platform Weibo. This video teased about the product.  Furthermore, Vivo has not yet disclosed how they achieved this feat. Also, it is still a mystery how they developed the 120W super Flashcharge. It is also not really clear when this technology would be introduced into a commercially available smartphone. Remember that OnePlus was the first one to bring a 20W fast charge tech. In addition, it hit the 30W mark last year with the OnePlus 6T McLaren Edition. Soon after, …

Split Home Energy Meter Combines ESP32 with Microchip ATM90E32 IC (Crowdfunding)

Split Home Energy Meter

It’s always useful to monitor the electricity consumption of your house, as you can easily and quickly find out whether an appliance is suddenly consuming a large amount of electricity before finding out from your next utility bill. It can also help remotely monitoring if an appliance has stopped working and fix it as soon as possible, for example an electric pipe heater making sure your pipe do not freeze in a holiday home. In many cases, a qualified electrician needs to be involved for the installation of whole home energy meters both for safety and insurance matters. We’ve seen in the past energy meters fit easily into a circuit breaker box but they may not be suitable for all setups. I’ve previously reviewed an inexpensive digital clamp meter that you just need to clip on one of the wire connected to your home without having to mess with dangerous voltage and current, nor worrying about UL or TUV certifications. …

$54 ZMI MF855 is Both a Power Bank and a Portable 4G Wireless Router

ZMI MF855 4G Router Power Bank

Tiny routers usually come with at least one USB port that allows you to connect a 3G or 4G cellular dongle, and since it’s often used on the go, or as a backup solution it makes sense to have a battery in the router as well, as was the case for Marstek MPR-N9 I covered way back in 2013. Xiaomi ZMI MF855 portable wireless router offers the same function but with an integrated 4G modem, a larger 7,800 mAh battery that can also be used to charge your other device. The router looks like a standard power bank from the outside. ZMI MF855 router key features: Cellular Connectivity 4G/3G and 2G networks Micro SIM card socket FDD-LTE bands – B1 1800 B3 2100 B7 2600 MHz TDD-LTE bands – B38 1900 B39 2300 B40 2500 B41 2600MHz WCDMA bands – B1 850 B2 900 B5 1900 B8 2100 MHz WiFi – 802.11 b/g/n at up to 120 Mbps Support for …

ATORCH USB PD Power Meter Comes with USB type-C, type-B, and type-A Ports

ATORCH J7-c

Most smartphones are charged over a USB port, and many single board computers are powered by a micro USB or USB type-C port, and USB power meters such as USB Charger Doctor can be useful to evaluate phone chargers, as well as measure power consumption of SBCs. With the launch of the USB type-C connector and features such as USB PD (Power Delivery), old USB power meters are not adapted to the new standard since the connector and most importantly voltages are different, so we need USB PD compatible meters like Satechi USB Type-C power meter. Today, I decided to look for more options on Aliexpress, and you’ll find many USB-C power meters with the cheapest models going for under $5 shipped. However,  ATORCH J7-c model caught my attention since it supports both USB type-C, micro USB type-B, and USB type-A power sources, so you can keep using the same meter for all your USB testing needs. ATORCH J7-c USB-PD …
