content: hi..please let me decide which psu to buy in 2025 ? it will be a slightly more expensive upgrade so i decide ask electronic masters here again.I need psu for repair laptops,mobiles etc.. i need 19volts on channel,0.9 volts for inject voltage,4-5 volts for phones,and last channel with different voltage if need..so 4 channels will be good..dont need always reconnect cables.. my sugon 3005d psu is faulty now.i also think Rigol DP2031

content: Much more expensive from Aliexpress, especially with the $200 shipping fee, than buying from local test equipment sellers here in the US. Price is about the same, shipping is free.

content: For shipments to the EU, Aliexpress includes local VAT into the prices so nothing needs to be paid upon delivery. This works very well. You should check if the same applies to the UK.

content: Quote from: nctnico on March 11, 2025, 08:06:19 pmDoesn't EU have a ~150€ limit on pre-paid vat ?Above that import taxes also start to apply, and the amount have to be calculated by customs/mail/shipping-company.

content: Quote from: jaaa1976 on March 11, 2025, 08:58:13 pmBe sure it's a PSU with fully isolated outputs, from each other and from PE.

content: Quote from: jaaa1976 on March 11, 2025, 11:13:57 pmOnly Rigol has some models with outputs which aren't isolated from eachother. This is very unusual though. I have yet to find a bench PSU which has no isolation between the outputs and PE.

content: Quote from: bingo600 on March 11, 2025, 08:37:49 pmWell, for me, while being logged in with an account set to the Netherlands as shipping location, the Aliexpress listing says the price is including VAT.
