Yes, in theory around 40% -> 50%, with it fluctuating over time.
However in practice imported electronics tend to cost up to about 100% then their original price abroad for several reasons, usually but not exclusively related to difficulties in 3rd world countries e.g. bribes necessary to get the shipment, insurance over shipment theft, margin risk due to volatile forex, etc
For example, atm an iPhone 14 costs 800 USD in the US Apple Store and 7600 Brazilian Reais in the Brazilian one. With the current exchange rate at ~5.20, that's around 80% more. Not that bad actually, that ratio has been worse in the past.
