Plenty of people have sent electrical items to Phils without issues.
Solely in terms of voltage there is usually no major problem for many items.
Problems may arise mainly due the differences in frequency, and also on occasion due to neutral and earth wire configuration.
UK is 240V@50Hz
Philippines is 240V@60Hz
When the required power is low, say for example less than 50 Watts, then it's virtually a plug and play scenario.
There's also plenty of other equipment such as computers, chargers for phones and camera's and the like that are actually designed to work safely with a range of input voltages and frequencies.
When this is the case it will almost certainly be indicated on the equipment somewhere.
It's interesting to see by simple calculation, { [(60Hz – 50 Hz)/ 50 Hz] * 100 = 20 % } that plenty of appliances/equipment will run 20 % faster than their normal rated speed. This may not always be safe if insulation and windings burn-out.
There's also quite a lot of equipment these days that have some or other form of electronic timer or micro-processor control system.
Such devices will at best run 20% faster than they are designed for. This may or may not be a problem, but it certainly makes electric alarm clocks pointless and you'll also need to develop new recipes for your electric breadmaker or microwave
Some washing machines may well work without major issues for a time and others will very soon not work at all. Depends on the motor configuration and internal wiring.
All similar 'motor-driven' appliances are going run 20% faster and produce an equivalent increase in heat output. Period.
My advice would be to seriously consider the likelihood of problems, the age of the equipment and cost of shipping versus the cost of buying new in Philippines.
If in doubt always double-check. Not only for the protection of the equipment but also for the body.
Most newish TV equipment will operate on either 50Hz or 60Hz frequency, but there are still many that don't. If it does not automatically adapt, the different frequency is highly likely to affect the refresh, rate and picture quality.
Again, many of the newer TV's have built in capability to switch from PAL to NTSC, but not all. Do your research, ask the manufacturer and discover how the 'switch' works if it's not included in the set-up menu.
Many freezers, refrigerators and plasma TV's do not travel well. Again some simple self-research or technical details from the manufacturer will help you in your decision making.
Don't pay high shipping costs for such items when the risks outweigh the benefits.
