Bit of technical knowledge is must to do this task.Yes its not a hard tough job.
OK there is generally nothing "Special" about mains, wall power supplies, they simply provide DC volts, via a step down transformer, or switch mode technology, now there are ONLY three important things to know and they are, the Voltages, and Amperage, and Power Plug Polarity.
You can often find this A: In the manual under Power Supply Specification, B:Or on the Actual power Supply itself, If one looks carefully, there is always on a UL listed power supply, the Output Voltage & Amperage, often Polarity is indicated too. If not, that can be inspected usually, by looking besides the power input socket, on the actual unit, and, it usually, has a little drawing, with a dot and a 3/4 circle around it, with a + & - showing what goes where. In almost all occasions, though, it is Positive to the CENTER, & Negative to OUTER, (or earth). All you have to do, is get any other power supply that has the SAME Voltage and Current rating, IE: 12 Volts @ 2.5 Amps. Now any 12 Volt supply that gives, the same or MORE than 2.5 Amps will do. You just need to ensure that the Plug is right, often the plugs are different, that too, can be overcome, simply, by cutting off the OLD, plug, and cutting off the NEW plug, and joining, Old, to New end on PSU. Again, usually, Positive is the Center, and the Negative is the Outer. Right go get that supply. Ebay or Radio Shack, are good places to start. Also any other "Laptop" power Supply that has same specs as described, will also work. As a matter of point, switch-mode is generally "Cleaner" power than a transformer one.But it is NOT critical. All laptop, and some other things, power supplies, have "Chips" in them, to "Help" with charging? that's what "they say" Sometimes, you cannot replace this type of power supply, with anything other than the exact replacement, BUT it is still worth a "try" it will/should not ruin anything all that may be compromised may be the "Charging" of the/any battery. That is why batteries can "Fail" and cannot be recharged, NOT due to the batteries actually being "Faulty" oh no, it is simply that the "Chip" has failed and that often, stops the battery from being "Seen" and/or recharged.
This details will help you to understand the basic theory.
Thanks.
