GeeekPi 10 inch Rack PDU, DC PDU Lite 7-CH 0.5U Rack-Mount Power Distribution Unit for DeskPi Rackmate T1/T0/T2/T0 Plus/T1 Plus/TL1/10 Inch Server Cabinet, 7 Outlets, w/3PCS 25cm DC5521 Cables

TLDR: I love it. would buy again. A luxury that makes a real difference. Super! This helps me power every random 12v thing on my rack. Switches? Check. Modem? yeah, that too. Fans, usb hubs, and hdd enclosures. It can power anything 12v, or probably 9v, 5v, whatever you might need, it could probably do within its rating. Just make sure you only hook one voltage device up for the input, and the outputs, and make sure they're all the same.

There aren't many options on the market for 10" rack setups, so I'm grateful that they're making this. I think it's a little pricy for what it is and its power limitations, but a nice addition to my home-built 80/20 10" server rack. Love the physical switches.

Horrible product. Horrible customer service that gives dangerous advice. After testing with raspberry pi 4 and 5 it does not provide enough power, which on paper it should. When booting a pi4 with 5” display, retro pi gives a low power warning (see pic) and it fails entirely to power on a pi5 with ssd hat. I supplied the pdu with a 5v 10a power supply and even with only one channel on it doesn’t supply enough power to the pi. Horrible customer service, do not listen to any advice or directions they give. They told me to supply a 5v device with 9v of power and then wanted my personal address and refused a refund and wasted weeks of my time. overpriced for the functionality it provides. and now the search continues for a 10” pdu.

Only worth it if you only need the exact barrel jacks it comes with. I have HP elitedesk G5 mini PCs with the 7.4mm barrel jacks and I have ordered about 30 adapters and cables so far and none of them will carry enough current from this thing to boot the computer, same goes for my DAS box with a different connector and adapter size. And even if they were working, the wiring saving is not that much. I am just going with a 1U shelf for the adapters.

I'm continually impressed with the ideas this company has for innovative products. If you are building a 10" rack setup and everything you are installing in the rack uses barrel plugs for power, then you need this. 7 "channels" of power, each with it's own on/off toggle switch and LED, please each channel is internally protected from overcurrent. Each channel has a barrel jack on both the front and rear of the PDU so you have your choice of where to connect the cables (or you can use both, but be aware of your power draw per channel). The connectors are all 5.5x2.1mm connectors, and you get 6 cables (3 short, 3 longer) plus some 2.1mm to 2.5mm adapters for plugging into items that have a 2.5mm innter diameter plug. How it works: You provide your own power supply at whatever voltage you need (up to 24V), for example 12V or 5V, and plug it into this PDU. This unit will distribute that power to all 7 channels. Note that if you have a mix of 5V, 12V, and/or 24V devices, you'll need to power them individually or use multiple PDU's, each for one voltage level (Be careful with this approach so you don't plug something into the wrong PDU!). This is quite small. 10" rack amount, half-height. You can mount it on the front of your rack if you like to have access to the switches and/or status LED's, or mount it on the back where it makes it easier to feed power cables to your devices and to save space. PROS: Small, 10" 1/2 height form factor makes it easy to find a spot for it in your 10" rack Power in/out connectors both on front and back for flexible setup options Each of the 7 channels has a power switch, status LED, and overcurrent protection (that resets after 4 seconds) CONS: Would be nice to have a bit more current handling capability 6 cables included but there are 7 channels, of course you can use your own cables I would think this device would be essential for almost any 10" rack project using devices powered by low voltage.

The internal voltage drop (.5V) makes this completely unusable for raspberry pi's (which is clearly the intent; "Pi" in their name). If you're going to produce a PDU for pi's that requires 5.5V input to function, you could at least have the decency to sell a 5.5V supply.

This company makes some nice and interesting devices and products and this one is no exception. Great power distribution if you need to provide power to a bunch of similar devices in a server rack so maybe a rack of raspbery pi's or other devices that require the same voltage or power requirements and you don't want to take up more outlets than one or two. Main downside is that all devices need to be the same voltage so don't think about plugging in a 5v device if you have a 12v supply hooked up to this.

This has been great! It Runs most of my devices in my 10" server rack! Each of the 7 connections can be plugged into the front or the rear making this very flexible. Im using a 12v LRS350w switching power supply and have 4 or 5amps per channel inline fuses. Haven't had any issues with connected devices and never tripped a fuse. Love it!
