The question to answer is arithmetic before anything else: the output must match what is printed on the tool, and a good third-party listing publishes both that figure and a model list.
The BENSN charger on this site publishes an output of 12 V, 0.4 A and names around thirty compatible Braun references. It also states, in its own text, that it is not an original Braun product.
That disclosure is worth more than it costs the seller. It tells you the compatibility list is the seller’s claim rather than the manufacturer’s.
The MEROM charger goes further in one respect: it states in writing that it is compatible only with the four models it names.
What to avoid is a listing that gives a brand and no figures. Without an output voltage there is nothing to check, and the wrong voltage is a failure rather than a slow charge.
Check your own manual before you follow anything here. Temperatures, water ratings and supply voltages differ from model to model, and the maker’s own figures take precedence over anything written on this site. A supply of the wrong voltage is a failure rather than a slow charge, and the figure is printed on the tool — not inferred from a connector that happens to fit.
