YiHi SX Mini regulated mod
Today I take a look at the YiHi SX Mini regulated mod.
I have been a long term fan of the YiHi series of regulated chips for a while now. Finally YiHi have released their own regulated ‘box’ mod, powered with their chips.
Arriving in a sleeved hard cardboard box.
Inside we have our mod, cushioned in a foam insert.
In the lid is an envelope, containing the quick user and the serialised warranty card.
As well as the SX Mini mod there is a USB charging and data lead.
The device has a sculpted face panel, recesses on the edges and a curved top where the fire button blends into the 510 connection.
The body is in two main parts, the panel and body. The body is lightly sculpted at the top, just below the 510 connection.
The 510 connection is a raised ‘plate’ which has small air channels in it.
In the base is a screw in battery negative cap. The base is quite flat, allowing the mod to rest securely on the base.
The mod is upgradeable (firmware) and can charge the battery via this USB port.
The 510 pin is brass and self adjusting (up to 4.5mm)
The fire button is long and wide, it can be pressed from any angle even on the edges.
Above the USB port are 2 buttons, these act as up and down for menu, memory and power features.
The bottom cap unscrews easily, or a coin could be used if you prefer.
The inside of the cap has a raised center to contact the battery negative.
It screws into a brass tube inside the SX Mini. YiHi tell me that this tube will be how the extension (to allow higher power) will attach.
Inside, at the top of the inner tube, is a spring loaded positive contact. This allows for any variance in battery length of your 18650s.
The display is large and clear, it has many pieces of information on it. Most of this will be familiar looking except the bottom line. These are your usage counter in Joules (measurement of energy , watts x seconds), which memory you are on and lastly the power mode (there are 3)
And lastly a couple of photos with my Loki Odin dripper on it.
I should say a little more about the menu and features…
The SX Mini uses both gravity and button presses to change menu features. The gravity method is just tilting the device one way for up and the other for down. People preferring buttons can forget the gravity feature and use buttons instead.
The device has 3 power modes, powerful/standard/soft which change how the power is applied. This is best explained with this picture.
Powerful starts a bit above the set power and reduces down to it, Soft starts a bit below the set power and increases to it and Standard just fires at the set power.
There is also the memory feature. There are 5 memory slots, each can be set to your preferred power settings and recalled quickly via the menus.
Another menu feature is the display orientation, this can be set to left, right or auto. Auto uses the gravity sensor to change between left and right depending on which way up the device is.
There are a couple more menu options but those are the main, important ones.
So, opinions …
OK so I am going to tell you the things I don’t like much, but I will start by first saying this is my favourite regulated device reviewed here so far.
That said , the device isn’t perfect…
The 510 is self adjusting and will adjust to a maximum of 4.5mm. This is a tiny amount less than I would have liked. In a collection like mine there are one or 2 atomisers that are longer than 4.5mm on the 510. Namely the notoriously long Magma dripper and the new MMVapors OverOne dripper. They are 4.8mm and 4.7mm respectively, and they sit just a little off flush on the SX Mini.
The corners on the bottom of the device on the control face, just below the USB port are a little ‘pointy’. Nothing major but noticeable in large hands such as mine. Some ‘profiling’ there, just a little curve, would make this device more comfortable.
Neither of these issue is a deal breaker though and as I said, this is still my favourite regulated mod that I have reviewed so far.
Now there are many things I do like.
The battery swap is virtually tool less, I can unscrew it with my thumb, you might want to use a coin though.
The button is well placed and comfortable to use in either hand
The overall design (except those corners I mentioned) is very comfortable to hold.
It is small and light, measuring only 94x42x25mm and weighing only 148grammes.
I love the usage counter on the display, it measures Joules rather than seconds, and resets with a battery change. This is like a trip odometer on your car, measuring use rather than drive time. It also will show up a battery that is under performing due to it being near then end of its life.
The auto sensing display that changes from left to right handed as I tilt the device.
A few more specs for you now.
The device is rated up to 60watts as stock, will do 85watts in ‘bypass mode’ (with the USB charging it) and can even do 100watts if you buy the optional extension to make the device dual 18650.
It will go as low as 0.15ohms with a maximum 3ohm limit. It outputs from 1 to a massive 9.5volts and 40amps max. 93% efficiency is also not bad.
The full specs are here
The firmware is upgradeable and the specs will most likely be improved upon with these updates. YiHi has an excellent track record of actually delivering these updates as well.
The device has a full one year warranty.
All in all, a great mod with a few minor places it could be improved on whilst still being loveable. Profile those corners and add 0.3mm to the 510 adjustment and I would be using this all day, every day.
I am seeing these in online stores for $190 (£150) at the moment.
More information is available from the YiHi website here
The site has also has an authenticity checker (via the warranty serial number) and the software/firmares to upgrade the device with.
