Description of MakerFocus Raspberry Pi 4 Battery Pack UPS, RPI Pack V3 Expansion Board Power Supply Type-C for Raspberry Pi 4B 3B+, 3B 2B+ with USB Battery Pack Raspberry Pi Support

Support charge while discharge: It will not affect the output of UPS power supply when external power outage. Note: If you use UPS to supply power for Raspberry Pi3b/3B+ when it is charging, please ensure that the input power is not lower than 2.5A. Recommended Use: 3V 2.5A power supply. ★Document link and Assemble video: Please get the link from the product description below. Two power modes: Outdoor portable model and Indoor UPS power Supply mode: 1) As an outdoor portable power supply, the motherboard is powered by a lithium battery. and he maximum external power supply capacity is: 5.1V. 2.5A. 2)As an indoor UPS power supply mode: MicroUSB plugs into a normal 5V 2A power adapter, and the external output interface(USB-A interface) can output a maximum of 5.1V.3A. Battery size: 70mm x 41mm x 9.5mm. 4+2LED are designed to show the status of battery power, charge or discharge: 1) 4 Battery power LEDs: Used to show the current battery voltage and power. 2)Power LED: When the switch is turned “ON”, the LED is lighting, and when it is “OFF”, LED is off. (used to check whether the power is supplied externally). 3) Charge charging indicator LED: When the UPS is externally charged via the MicroUSB interface, the Charge LED starts to work. With Protect Function: the external output port has a self-recovery fuse to prevent the raspberry pi from burning due to an external short circuit. 1) 5V.3A self-recovery fuse: When the two USB output currents total 3A, the self-recovery fuse will be blown. When the external recovery is no load. The 5V output will be automatically restored. 2) PMU over-discharge protection: When the lithium batter voltage is lower than 2.8V, PMU believes that the battery has been over-discharged, it will automat. Two Output Modes: except for the regular output via the USB port. At strong currents, such as for high loads above 2.5A, the drop in voltage on the USB cable is a problem that can not be ignored. So we provide a 2.54mm head as gift, which is soldered to the Raspberry Pi GPIO 5V interface for direct power supply, to minimize the damaged cable and pressure drop. In the high-power applications, cable damaged will cause lighting bolts on the RPI, you can weld the head to the 2.54mm header interface.

Either it's not a UPS, or it's defective, or I'm using it incorrectly.

I admit the possibility that I'm doing something wrong, but I doubt it a little. Two nights in a row I left my Pi 3 connected to this board via USB while keeping the battery charged. At some point on both nights, the battery apparently stops charging, causing the Pi to drain its battery and eventually die. When I buy a UPS now, I assume I'm buying something that will allow my equipment to continue operating for a period of time during a power outage and then switch back to normal power when…

Pros
  • Very good price
Cons
  • Upgradeable

Update: The replacement works great. Customer service is amazing! (Alt:) Reinforces things. Just not v3 Pi.

UPDATE: Makerfocus contacted me and after several emails decided it would be best to send me a replacement for testing. This battery works with the limited tests I've run (playing YouTube videos through Raspian; no hardcore gaming or 1080p video yet) without the occasional low-power lightning bolt icon I usually get. I'm assuming the battery life won't hit the hours like a cellphone when watching videos or playing games, but: a.) So far it's working EXACTLY as intended. b.) The company…

Once I figure it out it's great

This was a new adventure for me as I just got an RPI of 4 for Father's Day. I set it up as a file server and had to get a UPS for that. For the price and the features it had, I felt this device would suit me. However, the images shown do not explain exactly how the connections are made between the UPS and the RPI. With a little help from other users, I was able to determine that I needed to connect the RPI's power connector to the UPS and connect the UPS to the RPI from one of the USB ports to…

Pros
  • Sleek design
Cons
  • Having trouble

No battery low voltage protection -- EDIT: This has been fixed in the new version!

I loved this power module but it has two downsides, one serious, the other not so serious but still an oversight. The first big one: It doesn't have under-voltage protection for lithium batteries. If you leave your Pi on, it will eventually turn off, but will not shut down the circuit to protect the battery. You can see the LEDs pulsing as he tries to stay alive, the voltage is well below what he can handle. The main problem is that this will completely destroy a lithium battery if you let them

Pros
  • Easy to use
Cons
  • Everything OK

Works great as a UPS Raspberry Pi

I have several Raspberry Pis that run 24/7 and one fails every time the power goes out for a second or more. I figured the solution would be as simple as connecting the AC adapter to the battery and plugging the AC adapter into the Pi. The problem is that most power banks I've tried don't have pass-through charging and can also interrupt the power supply to the load when the charger is switched on or off. I'm sure there are solutions using an external battery, but I haven't found any. However…

Pros
  • GOLS certified
Cons
  • Empty

Not ready for rpi4. Good for rpi3.

Bought v3. I have tried very hard to please this device, especially the advertised features. But in the end he is not ready for RPI4. Advantages. For rpi3 it works fine. Seamless. Plug it into the cable, turn it on and it's gone. Provides enough voltage not to trigger a low power warning. Battery life is decent and the removable battery is a plus. minuses. The power connector is in the center of the board, just below the battery. Without lots of double-sided foam tape, you run the risk of…

Pros
  • Few competitors
Cons
  • not reliable
