hashwhy MicroUPS 5V 3A for Wireless CCTV Cameras | Upto 15W Output | 7500mAh Li-ion | Black | with USB to DC Cable Set

It's easy to install and use this micro UPS. I am using it to power an RPi 3B which in turn runs an arduino via USB port. I just had to plugin the micro UPS between the DC adapter (which was originally powering the Pi) and the Pi itself. It is providing adequate supply and working smoothly since installation about 2 weeks ago. Currently the Pi is showing an uptime of 7 days. During this period we have had several occasions when the power was off for over an hour.Made in India. The Hashwhy guys followed up receipt of the order via whatsapp messages with prompt responses.Wishlist:1. Will be good to have an i2c connection to the UPS to monitor the battery status2. Visual indication of battery level and charging condition

The media could not be loaded.  Stopped working after few days. Purchased as it was made in india. Not expected it will die in few days. Can't claim warranty too.

I primarily bought this to be used as a ups for my raspberry pi and have been using this for a few weeks now. It does work well and is able to keep the pi powered when the electricity goes out. Im able to charge it with the official 15w type ç power adapter from raspberry pi as the unit can handle this power as per specifications.The output power is also upto the mark as i did not see any power warnings on the pi.The build quality is not so good but as long as you dont mess with it, i think it will hold.One place for improvement would be the battery indication lights - There is no way to know how much backup is remaining due to which i'm always forced to shut down the pi after 1 - 2 hrs as i dont know when the battery will run out. Adding some leds to show the battery level would have been nice.

Good backupPowers up Raspberry Pi 4b 8gb Ram along with an SSD connected via USB 3.0So far so goodExcept the body finishing.There are gaps, melted plastic, uneven fitting and finishing.Get these things sorted and it’s a 10/10 product.

Used this for Raspberry Pi 4 8GB version.. the voltage and amps are fine.. not getting voltage warning like other power banks.However there's an important feature missing.. remaining battery status indicator.. it's impossible to determine how much battery charge remains during long power cuts..It defeats the purpose of relying on this device for worry free long hour backup.. am forced to daisy chain this device to yet another power bank.. not sure how difficult it would have been to add few more LEDs and a charge control circuit..

Product does what it claims - I'm using this as an UPS for my Raspberry Pi 4 server - Currently I couldn't test "How long it can power up Raspberry Pi with the 5000 mAh model " . But I just tested the "switch-over" and it is seamless - There is no downtime during the switchover that's and major advantage when using this for an Home Server !

The media could not be loaded.  The product works for the exact reason i have bought it for. My wifi camera works fine without any power failure. The built quality is good. The product looks very decent and very small size which occupies less space.

Just 4hour back up upon fully charged for my qubo camera which mere take 5v/1A - 5w.They say it is 10000mah , but doesn’t seem soNo value for money , too pricey for 4 hour back upYou can get 20000mah power bank and get 24hr back up on qubo camera only downside us ups.So apart from ups part , it is no value for money!Think before you purchase!!!!
