Qi Wireless Charging Standard Receiver Module 5V 1A PCBA Board Coil, Qi Standard Wireless Charging Board With Coil for DIY Cell Phone Charging Kit

Works well, if using in your own projects other than phone charging then avoid switching inductive loads with the power on, it will blow the receiver logic.

the items themselves work appear to be well made and do transfer power via magnetic fields. the transmission area and range are quite small (as expected for items this size) and takes some work to get fits and alignments right. one point of note the ferrite plate on the transmitter is fragile be extra carful when handling it and do not try to force it in to a housing if it doesn't drop in and lie flat make the housing bigger. i broke mine and the result was a reduction in transmittance to an already short distance making it useless for my project (totally my fault not the product) apart from that the product dose work would buy again.

The Receiver Module just about makes it to 5.01v using my CC load @0.8mA above 10mA load the 5V drops to 4.98v, 50mA @ 4.94V, 100mA @ 4.90v , 120mA @4.88v 140mA @ 4.65V not stable, 180mA @ 3.99 - 4.02V, 200mA @ 3.7mA, But can no longer hold connection. Not all tests with 3mm gap at prime coil to coil position. I dont see any QI requests from the receiver asking for voltage change as per the QI standaerd back scatter scoping the coil. My results show that this device is not faulty just not fit for 5v @ 1A.

Fragile

While there isn't anything wrong with the module I can't say there is anything overly special. The price was decent and they do exactly what they say they do. They should work just fine in a project as long as it isn't trying to go through anything to thick.

Lieferung ist in Ordnung, sonst auch technisch ist daran nichts auszusetzen!
