Argon Micro USB Cable Power Supply 5.25 Volts 3 Amps for Raspberry Pi 3 and Zero Boards | UL Listed | 3.3 Feet Long Cable with Micro USB Connector | Micro USB Cable and Wall Charger

Using the standard 2.5A power adapter with a wired mouse, a wired keyboard and portable HDD attached to the USB ports, my RPi 3B always had the low voltage warning on. A 3A power adapter like this one seems to solve my problem.

Awesome power supplies.

Worked like a charm and no longer have the thunderbolt light! recommended

This power supply has completely eliminated UnderVoltage issues on a Pi 3B+.

Ahh!! finally. I tried a bunch of chargers, plugs, wires, and finally decided to try this. I use 2 SDRs on my Pi and noticed even with 5v 2.5A usb chargers I would get lightning bolts on boot or when im doing heavy tasks. with this I finally noticed when I boot I dont have any issues.

doa. doesnt work.

Very well made. Heavy cable made to last

I never write reviews but was tired of the lightening bolt warning on 2 different adapters. just got this and no more lightning bolt. and some of the games that were laggy (probably because of underpowered Pi) are now working at full speed

I got this because I was seeing under voltage warnings from my Pi 3b+ with a 2.5A Rhino brand power supply. This fixed it so Im happy.

This power supply has plenty of power and runs very cool. Recommend to any one having a problem with low voltage..
