Due to many travel activities my old travel adapter had to be replaced. This should combine many functions where possible, so that as little as possible can be taken. The solution for me was the Skross adapter: - Three-way socket. - Locking of the contacts. - Adapter for other countries bays. - USB charge for mobile phone (the adapter also charges iPad !!) The quality is unparalleled. Certainly the adapter is not exactly small, but because other adapters are replaced, it saves space anyway. Only South Africa, I'd have to use an additional adapter. In my view, a clear recommendation. The website of Skross provides further information. Attention, note when ordering the exact name, because must be made between Pro + USB and Pro USB.
