Photos show what amperage it the relay requires to operate at different voltages
Minimal voltage to active coil is 7.6 volts
Lowest voltage to keep relay active is 2.4 volts
I've encountered poor quality 30/40 amp relays in the past that had a cheap micro relay inside. These are glued shut, but they are heavy for this type of relay, so they appear to have a good coil inside.
Last 2 photos show this relay (right) next to a 80 amp relay (left). It is the size of a standard automotive relay.

The relays are sealed well so you don't have to worry about water intrusion in the relay itself. The included wiring is a nice bonus, but it is NOT sealed so water can still get into the connections. Also the wires that are included maybe on the small side for any sustained high current, certainly not suited for a continuous 30 or more amp load.
Luckily the terminals are easy to remove from the connector so heavier wire can be installed and still look professional.
The mounting bracket is a bit flimsy but holds the relay in place.
For the price you cant hardly go wrong, certainly much cheaper than buying them at a local parts store.
Update 10/5/23
Been using these for several years now and only had one failure so the relays themselves are pretty good, specially for the price.
Just remember the included wires are NOT up to the task of a 30 amp load, even if the relay is.
The wires are marked as 16awg which is OK for up to a 15 amp load, depending on the length of the wire used in the circuit and how much voltage drop is allowable.
Have successfully used for electric radiator cooling fans after replacing some of the wires in the relay connector.
Personally, I make new wires for the power supply side and the load side of the relay (terminals 30, 87 [& 87a if it is being used]) if the load is over 10 amps. Terminals 85 & 86 are fine since they are just used to activate the relay and that does not use much current at all.
As always, make sure any hot wires are fused with an appropriate sized fuse for the wires and circuit load as close to the battery as possible.
Relays are still 5 star, specially for the price.
The wiring and connector would be more like a 2 since it is so far below the rating of the relay, but again, for the price you can't expect much. At this price point, you are lucky to get a connector at all.

Wiring harnesses also seem to be well built.
Just an FYI, even though the relay is rated for 30A, doesn't mean you should run 30 amps through it. As others have mentioned, the wiring harness included, is not rated for that high level of current.You should always factor in, 'the weakest link', i.e. if the wires feeding the relay will not handle more than say 8 amps (and I don't know what these wires will handle), it doesn't matter much how strong the relay is, you don't run more than 8 amps through the wires.... duh. and even that is pushing it. When an overall circuit is rated for 8 amps max, you should not get anywhere near 8 amps anyway. Pushing anything to the max is never a good idea. Besides, running high current through a mechanical relay, the contacts will arc, carbon will build up on the contacts, the contacts will become pitted, and eventually.... one day, when it energizes, the contacts will stick, and whatever it is will be 'On' continuously... if it comes on at all. You might want to consider using a solid state relay (DC) or a triac (AC) imho.
Any time you are dealing with any type of high current, get someone that has an electrical engineering degree or background to look at your circuit designs... just because you may know how-to, doesn't mean you know how to.
One of my kids kept leaving their car lights on, apparently they have a lot on their minds these days. I used this to build a simple 'lights-on' circuit. This particular car doesn't have one. I found a line that goes to 12 volts when the key is turned on, and found the "Lights" wire. I wired it up, so if the lights are on, and the key is off, a Piezo Electric buzzer sounds. It is very low current, and works great. We haven't had another "accidentally left the lights on" incident since.
These are quiet handy for any number of little projects you might have.
