Quick answer
Is $19.15 a good price for Hall Effect Current Transducer QNDBK1-21 AC 50A 100A 200A 300A / 5V…?
It is the usual price, not a deal: $19.15 is in line with the typical price of $19.17 that DipScout measured over the last 14 days. It is the lowest in 14 days, but it has held this price since Nov 10, 2026.
$19.15
Today it costs $19.15 on AliExpress. Since Oct 22, 2026, when we started tracking it, it ranged from $15.29 to $19.19. It's the lowest price in 14 days, but it has been at this value since Nov 10, 2026; by our price history that is already the normal price, not a sale. Price checked on Nov 11, 2026, 08:01 UTC.
No drop compared with what we observed over the last 14 days. The store advertises "was $19.34", but that is the store's own claim; we only state discounts our price history proves.
