What else do I need to consider?
Ergonomics and usability are important factors. A cold laser that produces great results but is awkward, uncomfortable or difficult to use will eventually become an annoyance.

Weight and balance. This is an important consideration for handheld devices. Once you have an LLLT device then like many other practitioners, you will find yourself using it much of the day. A heavy device or one that is poorly balanced or difficult to hold can cause strain and discomfort.

Battery vs. outlet powered. Here we are looking only at the power source, not if the device is corded or cordless. Most class three lasers are battery powered. Some class 4 lasers are battery powered. In a practice setting, battery power has some advantage in that it can be easily moved from one treatment room to another without worrying having to plug into a power outlet. If your work requires treatment in the field as a sport physician, then battery power is a must.

Corded vs. Cordless. The advantage of a cordless device is that it provides unrestricted use and no interference with your patient. For illustration, if your patient is lying on a treatment table and you need to move from side to side, a cord dragging across their body can be disconcerting at the very least and can even interfere with the treatment. Due to the power requirements of some Class 4 lasers they are not available as a cordless option. Class 3R and some Class 3B (up to 500mW) lasers are cordless. When evaluating a cordless model, ensure that you can get at least one full day of use at the maximum power setting.

I have some favorite portable lasers as these are the ones that I bring with me. They aren't Class IV as I can't bring those with all the time. There are 3 brands that I really like. One uses mostly infrared, the invisible rays can fit in my pocket and the other is LED handheld and the other one is huge but is not as portable but still is considered a portable. If you are interested in comparing the different portable cold lasers, please take my quiz here before calling me.

Update: I will not sell lasers that are not FDA cleared. Too many doctors have gotten sued since I started this site. I will let everyone know which lasers are now approved
I will never trash talk lasers that did not get approved or those that were never cleared with the FDA. See my requirements for lasers that are not FDA cleared.
