Ah, there is another trick to wall wort's. Who says you must use a stock hobby 50ma output. Go to an electronic store or buy online for the specs you want. Your input is 110vac and for output the same output voltage per TX or RX as your hobby unit but at a mah rate that you want per your desired C rate. For Eneloop packs that would 200mah at C10 or 1000mah/1amp for quick charge. Note many are dual rates so if you need both TX and RX, then you will need two different units.
Some wall warts are also multi output.
This is what I have been using for decades, and built from a kit form. Still works like day one;
There are also some that also have 110vac imput
