Questionably 20A. With screw terminals it's max 10A.
The IC on the board is designed for 20A. Without commenting on how they are letting 20 amps through a pair of pins, the screw terminal attached to the board is rated for 10A 300V, making the board as a whole 10A max. If you wanted more amperage you would have to desolder the screw terminals and resolder the appropriate wire into the hole.If you only need 5A max, go for the ACS712 5A version. It's more sensitive than this board as a practical bonus. There is also a 30A version which would be better if your circuit gets close to 20A. Unfortunately I have a 12A max requirement so I'm stuck modding this awkward in-between board.

Not very accurate, lugs too small
The lugs are only good for 10a as others have pointed out.Also they don’t seem terribly accurate. The zero point wanders a little even when the shunt has a shorting wire across it. At zero amps the output wavers between +0.13a and -.03a - this is not a serious problem.The biggest problem is they’re inaccurate at least so far when testing below 3 amps. I’m testing them against a $12 handheld volt/amp meter though so I can’t say for certain which one is wrong. I got 1.6a on these devices and my meter read 2.3a - If it’s real and it’s linear I’ll fix it in software.

Received on time. Have not tested!
Original product Packaging (not the shipment packaging) was damaged with few units solders flattened. Tarnished solder pads. Will have to test for functionality and decide if to buy again.

Does not work with AC currents
I ordered the 20a device and relied on the description that the current sensor would detect both ac and dc currents. The current sensors I received only work with dc currents. Yes, they did work with dc properly.

Does not work with AC !!!!
Product description is AC/DC but does not work for AC.

Works OK, but Output Surprisingly Noisy
The sensor works OK, but do not expect a precision or stable measurement. From a steady input, the voltage output has a fair amount of noise you'll have to deal with, either in hardware or software.

Terminal blocks too small
Terminal block barely allow the use of 16 awg wire which is not sufficient for 30A. 12awg would be more appropriate.
