Hi All, Anthony Vapes back here with my review of GTRS Vboy 222w Dual 2x700 Mod. Please see bottom for disclaimers and links
Introduction:
The GTRS Vboy 222 is the latest mod from somewhat new manufacturer GTRS and is a Dual 2X700 mod (takes 21700 and 20700 batteries) that comes with adapters for 18650 batteries. It uses the popular yihi chip (SX520 chip). Following up on the original Vboy 200 which used the SX500 chip. It’s available in 6 colors, silver, black, red, blue, gold, and rose gold for the frame. All of the battery doors and front are black

Initial Impressions and features
When I first got this mod, i was pretty happy it was a dual 2x700 mod. The batteries have been out for a while but sadly most of the first mods that took them were junk and even the good one’s lacked a good temp control. So pairing the dual 2x700 configuration with a yihi chip was a solid idea. I wasn’t sure what to expect from GTRS, I’ve heard issues with the vboy 200 (mainly the battery door) but the GTRS 150 was solid even with a non yihi chip in it. I was excited to see the measurements of 31mm wide and a centered 510, sadly though there is minor overhang with a 30mm atomizer as the front and back stick out a little more. A 28mm atomizer will sit flush though. It’s got a simple shape and design that’s a rounded rectangle, nothing too fancy and the nice bright large color screen like the SX mini g class. Overall I was pretty happy with the mod form the start
Watt Mode Performance (chart and spreadsheet in picture album)
Let’s get into some data. I ran my normal testing, but since it’s a dual 2x700 mod I used the ijoy 5 leg 20700 Batteries instead of my normal sony VTC5A i use for 18650 mods. Testing resistances were done at .1072 , .1486, .2094, and .4816 ohms (yihi chips read resistance to 4 decimal places). wattage points were max (222), 200, 150, 100, 75, 50, and 25. At .1072 ohms it maxed out at 218 watts and 45 amps. For the rest of the testing it was never off by more than 1. At .1486 it maxed out at 225 watts. The rest of the tests it was never off by more than 3. For the .2094 test it maxed out at 210 watts. For the rest of the testing it was 7-10 high for 100+ but 3-5 high for less than 100. For the .4816 testing it maxed out at 116 watts and 7.469 volts. The rest of the testing it was also high 5-11 watts. The volts shows there is no boost circuit in this mod which i’ll discuss more in a bit.
Overall I was pretty happy with the performance of this mod. At under .2 ohms it was very accurate. Over .2 ohms it does hit a little high 5-10 watts so adjust accordingly. The most amps i got was 45 which is really good for a dual battery mod. The average is 40 overall but for dual 2x700 mods most are around 45ish but i’ve only had the pleasure of testing a handful of them (ijoy diamond, Vboy 222, RX2 27100, and geekvape blade) So it was right on par with that. GTRS does not list an amp limit but Yihi does for the chip and they list it at 40 which is conservative, but i’ll never complain about underrating a mod. Its accurately rated for power since it does do 225 watts. Now it’s time for the Lack of boost circuit. GTRS lists the max volts at 9.5 which means it has a boost circuit. I’ve tested the SX mini G class about a year ago (SX550J chip) and it also had a boost circuit. So i expected this mod to have one, I was pretty surprised when my testing revealed, there was no boost circuit. So after that I went to Yihi’s website to pull up the specs on the the chip in the Vboy 222 (SX520) and they list the max volts at 8.0 for that chip which means no boost circuit but also feels overstated since input voltage is 8.4 max and they list efficiency at 94% which means max theoretical voltage would be 7.896 however since batteries sag under load, we know it isn’t possible.
Simplified TL
R Performance summary
Mod performance is Good. Accurately rated for watts, underrated for amps, Overrated for Volts. Accuracy is excellent at under .2 ohms, over .2 ohms it hits a little high. High amp limit of 45, max watts 225, Max volts 7.469 so there is no boost circuit.
Temperature Control Performance (Temp mode is called Joule mode on Yihi Mods)
Using SS316 wire with the SS wire type and TCR set to 92, I tested 7 builds a single round spaced, a dual round spaced, and 2 fancy single coils and 3 fancy dual coil builds. Please note for Yihi chips like this you need to lock your starting resistance by holding in the menu button. There is power adjustment on this mod in temp control mode up to 120 joules (which for our purposes is the same as a watt but technically not the same as a watt). I found adjusting the watts does have a direct effect on ramp up as it should so well done there. The whole 222 would have been nice, but I feel 120 is more than enough for most and is the normal limit on all Yihi chips and I haven’t heard anyone complain about it. Temp control performance was excellent as you would expect from a yihi chip. The ramp up is good and adjustable, the throttle back is smooth. It feels accurate, i get a nice warm vape at around 450-460F as it should be. Most people will find their best vape in the 400f-480f range as it should be depending on how you like your vape (cool or hot), and the dry hit protection is great as well. Overall an excellent performer in temp control.
