Your opinion about this custom USB charger for vintage Calculators

Hi All,

The TAS site has the following auction. The auction sells custom made USB cables that will charge HP-35, 45, 65, 80, and 67. The seller explains the voltage and current provided by his custom USB cable.

Your opinion? Ok to buy?

This has come up before and the consensus was it won't hurt the calculator and will eventually charge it.

I've got one I use with a 45 and haven't had any problems.

Thanks Pauli!! I needed someone to give me the green light to buy such an adapter.



I've used one for several months. No problems so far.
