An hack would involve to replace costly components, just open the case and cry on it. a) DC operating circuits (99% 1000W) Devices which use components powered in AC (electric motors, heater resistors) or big main voltage transformer are almost impossible to hack or the business case is red. It's a very difficult task but it cleans up the air a little bit (I hope). Circuit classification I would start by dividing the devices in three big groups. If this is impossible to look at it don't risk, trust the main plug (and/or main fuse) to determine which is the main voltage and consider this device as not worldwide compatible. Hacking the device to work with the current voltage In this section we will investigate the possibility to get the device running with a different main power supply voltage The golden label rule First look at the label of your product, it should tell you right away if you need a hack or not.

I was starting to investigate the possibility to use a TRIAC to get the wave to max 110VAC (in some 110VAC device it could be a winner), but for business case and complexity doesn't make too much sense. Europe): Here no mercy, you need a transformer. Please consider also the circuit beaker Ampere size since you are now running more than a single device with it. In addition to that please check if have a dryer or a kitchen oven close where you want the 240V, as I saw those devices runs at 240VAC, so you can just tap the two phases out there.

A transformer is suggested because it is more safe. Please read before regarding so e safety issues. US/Canada): You can get directly the 240VAC for the main power line by tapping off the two opposite phases. WARNING YOU WILL WORK WITH HIGH DANGEROUS MAIN VOLTAGES! USE CAUTION AND THINK TWICE BEFORE ACT! Worldwide situation Genreally (99%): 220VAC 50Hz or 110VAC 60Hz for details check also how many main plugs are out there! Hacking the power lines to get the desired voltage out It also looks like generally the frequency difference 50/60Hz will not be a big problem. It could cost a lot of money or be lethal for you and/or the end user. I'm not responsible for any call to the local fire department or burned devices. I will try to keep the important information in this first page post. Forgive me if this is not 100% correct or need modifications/better technical descriptions. I'm just an EE with a little bit of passion and I travel a lot in the past in different countries so I build up a little experience on this stuff. After a little research I found almost nothing regarding this topic (only sporadic hack guide for some product). I was always wondering if it is possible to hack a 110V device (sometime it's so cheap tp buy in $, if the shipping/custom cost are reasonable) into a 220V one and vice versa. Well let them believe they can recharge the phone with the WIFI RF energy. Common mortal people think a main plug adapter like those ones: will solve all the problems. power limitation? BTW the buzzing noise drives me nuts. Guys, I know you can buy a 110V220V transformer, but is it not our bench already crowded enough? Is it a good idea to carry a heavy transformer in addition to the device you need? Why not to use the brain instead of money? And what about the max.
