I make it a habit that whenever something arrives with its own wall-wart or charger, I label that power-pack with the brand and/or model of device that it was supplied for. The number of times I have had to replace a broken charger/power-pack/wall-wart I could probably count on the fingers of one hand. But they are freely available when you need them. They even make multi-voltage, multi-connector 'universal' power-packs. Periodically I go through the pile and anything marked with an obsolete, broken or discarded device gets tossed in the bin.
