60 Ports USB Charging Station with Intelligent Protection, Multi-Port USB Charging Station Organizer for Hotel School Shopping Malls

I have multiple units. I it impossible to be in the room working all day with these on. The fans are just too loud. The closest analog I can make is that they sound like a crowd cheering at a stadium. You just can't be in a room 10 to 12 hours a day working with this noise.I have power supplies of similar or greater power that are efficient enough not to require a fan at all. Or, at the very least, a low speed fan that you can barely hear. My guess is that these are very inexpensive and, therefore, low efficiency switching power supplies that require such a fan to deal with heat generation.I will probably rip these apart, throw away the power supply and replace them with a good quality MeanWell or something like that. No fans. Just quiet power.Had I known this I would not have bought them.EDIT on 08/30/22.I finally had to have a look and took these units apart. What I found was disturbing. The power supplies used inside are cheap as can be. They are not UL, CE, TUV, FCC certified. Nothing on these units is.The power supply internal pictures do not match the images in his listing in a very important way: The heatsinks shown for the power transistors do not exist. No finned heatsinks inside. Also, the circuit board shows a heatsink for the bridge rectifier and it isn't there.The connections to the power supply, both from incoming AC power and DC out to the USB boards was terrible. I am in the electronics industry. IPC standard 610, in section 4, covers connections made when clamping a wire with a screw. Tinned wires (solder applied to the stripped copper end) are specifically listed as a defect in this standard. In other words, these devices would not pass regulatory testing as built.The reason for is that that tinned wires will have a tendency to loosen over time. This can cause overheating or even a fire. In a potential worst case, the wire comes completely loose and shorts against the chassis, creating a different type of hazard.I also had a look at the three circuit boards with USB connectors. The claims being made in this listing are false."Independent work: each interface has independent chip, effectively prevent the mutual interference between each port, ensure the safety of charging equipment."Not true. There's a device, that might be a resettable fuse (hard to tell because there is no way to identify what it is) connected every TWO ports. At best this is a current limiter. If the number on it is the current at which it triggers, it is 20 A. If you are passing anywhere close to 20 A through a standard USB cable you are going to have smoke or a fire. In addition to that, the soldering job isn't what I would pass for quality work at all.Another interesting quirk is that the data lines are shorted together on every pair of USB connectors. In other words, if you plug in a couple of devices into adjacent ports, their data lines will be shorted together (D+ and D- on each device are shorted to each other and to the other device on the same paired connector). It isn't uncommon to short D+ and D- on a SINGLE PORT. This tells the device being charged/powered to draw as much current as it wants without the need for negotiation with the device providing power and is covered by USB charging specification BC1.2. Shorting the data pins of two devices together (four pins shorted together) is likely a bad idea. There is no reason to do this.Because I am under a deadline and I am qualified, I simply threw away the power supplies on the devices we bought and replaced them with quality industrial-rated power supplies (side note: no fan required). I also re-soldered everything and installed proper wiring. In other words, I am not returning them because I just took what I could fix and discarded the rest. It would cost me more in time and money to buy something else, only to discover similar issues. Sometimes you just have to take the hit and make the best of it."Advanced protection, protecting your devices from electric leakage, short-circuit, overheating, input and output overvoltage, output over current, enter anti-reverse, flame retardant, overcharge and over discharge."Sorry, that's complete nonsense. Not sure how Amazon allows products like these and the claims posted on the listings. It seems selling quality products on Amazon is simply impossible because it is a race to the bottom. Oh, yes, and a metal shaving came out of one of the units when I took it apart. These things, for just over $100, are an accident waiting to happen.

Looks good, charger included.Thanks again, best regards, and recommend to all.- Cheers

I run a delivery business for Amazon packages. We need to charge our delivery devices and batteries every night. I have had this for 9 months in the warehouse.Once, a few weeks ago, we came in and the devices hadn't charged fully. The light was on but the charger wasnt working. The fan wasn't blowing. Later in the day I realized the dust on the fan had accumulated and instead of overheating, the unit stopped charging. This was a good thing, not a bad thing. So now I bought some canned air, and blow out the fan every 2 weeks. I still love the charger and have confidence in it.I have determined that maybe 1 or 2 of the 60 ports no longer work. For me, that's acceptable. I would buy another tomorrow if this one died tonight. But it won't!

Love this thing, have used it nearly daily for a couple of months in our test lab. So much better than 6, 10 port chargers. We sometimes get 250 devices delivered to our office, and most of them seem to on 10% Battery. Get an assortment of cable length to keep your devices tidy while plugged in. Would love it more if it told me a port was taking current, but for the price this is just amazing.

Great for large gatherings. Everyone can charge their gadgets

Great product! I use this to charge my GoPro batteries and extended batteries, all of these charge at the appropriate rate! Bud can of this unit. Definitely worth the money.

We use the G-daimler 60 Ports USB Charging Station for running our USB powered circuit boards overnight. We've had almost 600 boards running over 24 hours each powered by it. Typically 40 or 50 at a time, more or less. Our boards are very low power, only 90mA so this is not a test of the charging capacity of the charging station. Would buy it again, its worked without a hitch.

Super easy hook up , and every port is being used! Good buy, would buy again if I needed more I ordered like 4 of these. Not a single issues since purchasing.
