Elite still requires 90 day reporting and annual extension if yiu don’t leave Thailand that year. I think TM30 as well. Seems to make sense if under 50 and you are willing to pay the price. I got non O retirement, i think it was ฿2000 to start and its ฿1900/year, plus ฿3800 for multiple re-entry permit if you travel.
If all else fails, and you need to get this done, and agency can help you get an account without the certificate. Thai Visa Centre is often mentioned, there are others. When I open my account at Krungsri, I got the certificate from my embassy, American. However, nowadays, because of Covid, that may be more difficult or require an appointment in advance, check with your embassy Embassy
i researched for you. It seems the charger consumes up to 300w, so you epuld need a much more expensive converter. You can possibly modify the usa charger but it’s highly technical. If you plug it into the power here it will blow an internal fuse. However, Milwaukee tools are available here, with 240v chargers. There’s many on Lazada.
You can get small ones, but there are very few items they will work with. I have this one i bought in nyc, and Lazada has a similar one. I use it for a WaterPik. Most electronics are rated 100-240v, and don’t need an adapter. Thinks with motors or heaters would need a huge transformer, cheaper to get a new item here. And power here is 50 cycles, USA 60 cycles, motors will run at a different speed.
