I use an Omron model that's now a good 10 years old. It works on batteries or plug-in. Highly recommended.

When our power goes out we get in the car and ride around so I can have a/c. I also have a portable nebulizer I can use in the car. I also have a portable tank that does not always work as it should!!! So far no serious problems!!! I need to take vitamins but can't remember which ones are good for me! A-E-D and I don't remember the other one. If you know please share with me. Thank you and God bless.
