ChargerLAB Power-Z C240 Portable USB-C Tester, Digital Power Meter,

[@wwjoshdew]

OH my gosh! This was recorded late last night and I didn't realize my hands were so dirty. It's actually kinda triggering me, especially when my hands are so "zoomed in". I'm terribly sorry.

Seems the C240 is inaccurate by 3-7W in relation to the Anker 737 as seen in your video at 6:53 and 7:18. Meanwhile, the KM003C is accurate within 1-2W in relation to the Anker 737 at 4:15 and 7:52 and 8:14. Being off by a few percent is expected but being off by nearly 10% as at 7:18 is questionable.

I saw those errors in another review, chargerlab even has a warning on their site about C240 being not as precise as KM003C, it has about 300mA error, it's own power consumption mostly

Seems like it’s from the same manufacturer as WITRN but WITRN still does it better imo (packing more in the same size). I’d gladly pay $25 more for a C5 over this. Also there’s nothing wrong with your hands bro, you’re good! 😅

Why did you choose this model as opposed to the FNIRSI FNB58 or the AVHzY TC66C? Both of those have a greater range than 0-50W, and they have gravity sensors that rotate the screen.

Hi wwjoshdew, great presentation. Thanks. Is there a way to check the charge pack capacity? I think that is a valuable data too, so we can decide if the batteries inside the charge pack are done. Thanks.

[@NicksStuff]

Have you had the opportunity to compare them to the FNIRSI testers? Particularly the Fnirsi FNB58? It's half the price of the fanciest Power-Z and I can't seem to see any drawback on the specs

Nicely done! 😊

I came across your video while doing research. I have a question for you. I want to test the 20 Volt/12 Amps 240W SUPERVOOC charging adapter and find out its actual values. I want to measure directly at the adapter output and I want to measure from the cable output after plugging the cable into the adapter. The adapter has a TYPE-C output, 240 Watts gives the value as 20 Volt/12 Amps. I have researched a lot of products, there are products that see 240 Watts and can reach much higher Volt levels than 20 Volts, such as ChargerLAB Power-Z KM003C - Power-Z C240 or PLUGABLE USB C Power Meter Tester 240W, but these testers are not in the Ampere range of the SUPERVOOC adapter (I need 20 Volts/12 Amps, but I could find a maximum of 6 Amps in the meters I researched), so I think a healthy measurement cannot be made. What can I do about this, how can I reach the correct measurement, is there a device you can recommend?

[@etienneetienne4752]

How do you plug this device in non usb c iphones like 1phone 15 and below?

[@fredhinck9685]

None of these seem to support I phone. Am i missing something?

[@RoyalFizzbin]

Nobody has a meter with a lightning connector, if that is what you are asking

[@KatyInNH]

HI, I love that this unit has the Watt-Hours. Does the KM003 also somewhere show the energy? Love your channel! Thanks Katy

I have this tester. It is defective. It distorts voltage and current.

[@kuanjuliu]

Awww, it seems the accumulated Wh is lost when the power is lost, i.e. the C240 doesn’t have power-off memory. Does the KM003c allow recording through a power outage (power tank running down, etc)?

[@walterkeen7394]

its not acurate. its off by 7 to 10 watts. i have one and have the same issue

[@jimmyross1672]

lol yeah i wanted one of these for sure but i dont have 10 dollar to spend lol wish i did i need a job but im white and a felon so good luck to me and i live out in the woods wirh my mom so its even harder what im sapsot to walk to work lol 20 miles away i didtn think so
