A lot of LiPo chargers like the Q6 cannot reach their maximum output power and current when you’re running it at low voltage such as 12V. To get the most out of your Q6 charger, you need a 24V power supply.
Since the output is 24V, you can also use it to power your TS100 soldering iron :) It makes a great bench power supply :)
See this article to learn about power supply for LiPo chargers.
Where to Buy?
Banggood: http://bit.ly/400W-24V-PSU (12% off with this coupon: Adapter12)
- Input Voltage Range: AC 110-220V
- Output Voltage 24V
- Current: 16.6A
- Power: 400W
- Size: 222×70×38.8mm
- Weight: 670g
The Lantian 24V 400W PSU comes with a power lead with USA electrical plug, but you can easily get around with an adapter if you use different receptacles.
Both input and output are screw terminals.
Here is how to connect the input cable to the power supply module. It looks a bit confusing to those who aren’t familiar with electrical stuff I have to say, luckily my unit came connected so I didn’t have to mess with the live, neutral and earth wires. It can be dangerous if you get this wrong.
Not sure why they don’t just use standard IEC 60320 connectors which are commonly used in computers and servers PSU.
And here is the output terminal, connected to a XT60 pigtail with female connector. It has two sets of outputs so you can hook up to two different devices at the same time.
The whole enclosure is made of metal with heatsink on both sides. There is a built-in fan located near the output. The bottom is very smooth, I had to stick some “rubber feet” at the bottom to prevent it form sliding on slippery surface.
Powering LiPo Charger
The voltage output of this 400W Power Supply turned out to be slightly higher than advertised, at 24.6V. Not a problem for the iSDT Q6 chargers though.
I haven’t tried running it at its maximum 400W, because my parallel charging board only takes 4 LiPo’s. But running it at 270W for over 20 mins, it still stays stone-cold! Not even warm.
The Q6 is only 300W, so this PSU should be more than enough.
The only complain I have so far is how loud the fan is! Noise level measured at 66dB, it’s like having a vacuum cleaner turned on in the next room. The fan speed seems to be constant, I wish the fan is quieter or smart enough to change speed with temperature.
Not a 400W PSU
My charger sometimes stops charging when running higher than 250W, it seems like the PSU output is very unstable when running at high power, and the charger restarts.
If you are looking for a true 400W PSU, don’t get this one. This is a 200W PSU at best IMO.
It’s possible to build your own charger power supply from server or PC PSU. We have a few posts in the past to explain how.
- DIY PSU for LiPo Charger and Workbench
- Get a LiPo Charger Power Supply cheaply – 1000W Server PSU
However I really don’t see why you should DIY, since the Lantian 400W 24V PSU is quite cheap, and it works right out of the box. A pretty good option if you don’t mind the noisy fan :)
