Something to squeeze in the chair, and something to train with between visits
Verdict
A soft stress ball is the one for the donation chair. It is quiet, forgiving, and gives you something to pump rhythmically without straining. A grip strengthener with adjustable resistance is a training tool for between visits, and it is the wrong thing to be squeezing with a needle in your arm because the effort involved is much higher. Follow whatever your phlebotomist tells you about pumping, since practice differs between centres and between machines.
Most donors get handed something to squeeze, and most centres have their own view on how much and how often. These two products are not doing the same job.

Choose a soft ball for the chair. Squeezing at the pace the phlebotomist asks for is the point, not squeezing hard, and a foam or gel ball lets you do that for the length of a cycle without your forearm cramping. A set with different firmness levels is useful because the softest one is often the most comfortable to use repeatedly. Wash it periodically, since it lives in a bag and gets handled a lot.

Choose an adjustable grip trainer for use at home, not at the centre. If your grip genuinely is weak, working on it between visits is a reasonable thing to do, and adjustable resistance lets you start low. Do not take it into the donation chair: heavy repeated gripping with a needle in place is not what any phlebotomist is asking for, and it is a good way to move the needle.

Advice on pumping varies between centres and between machines, and the person watching your arm is the one who knows what their equipment needs. Do what they tell you and stop when they tell you. Anything unexpected in your arm during a donation, including pain rather than mild discomfort, sudden swelling, or a pins and needles feeling, is a reason to speak up immediately rather than waiting until the end. Tingling around the mouth or fingers is a known reaction to the citrate used in the process and staff deal with it routinely, but they can only do that if you tell them. This site tracks plasma pay rates and does not give medical advice.
If arm comfort between visits is the underlying question, the Copper Compression arm sleeve review covers what compression actually does and what the marketing on the packet does not support.
Muscle contraction in the forearm helps blood flow through the vein during the draw cycle, which can keep the process moving and shorten the appointment. The specific instruction, how hard and how often, comes from the phlebotomist and varies with the equipment. Squeezing constantly and hard is not the goal.
Bruising at the needle site is common and usually relates to the vein and the needle rather than to grip. Vigorous or erratic movement of the arm can contribute, which is one reason staff ask for a steady rhythm rather than maximum effort. If a bruise is large, very painful, or spreading, tell the centre.
Flow rate depends on the vein, hydration, the equipment and the centre's protocol far more than on grip strength. Being well hydrated is the factor donors actually control. If your donations regularly run long, ask the staff whether there is anything about your arm or your hydration they would change.
Tell the phlebotomist immediately. Mild pressure and coolness are normal parts of the process; sharp pain, worsening pain, swelling, or numbness and tingling in the hand are not, and staff are trained to respond to them. Do not wait until the end of the cycle to mention it.
