Klein Tools 93PLL Self-Leveling Laser Level, 200-Foot

There is a lot of technology in this level, yet it's so easy to use that it falls into that strange category of "high tech item a child could use." I was extremely impressed from this from the very first time I used it. The green lasers are very bright and easy to see except in direct sunlight and come on, what can you do it's direct sunlight you can still use it within a few dozen feet even at high noon. In a interior room with the lights down I was able to make accurate measurements at my nightclub to a distance of more than 200 feet. Literally just set it down, unlock the gyroscopes, wait a few seconds and then turn it on that's all you need to do. One of my staff has a Bosch that cost three times as much as this, and this seems to do exactly as well. It comes with a robust carrying case, and adapter for different tripods, the battery life has been fantastic I've only had to charge it once since I bought it, and there's not a lot more I can say about this other than it far exceeded my expectations. Lately I've been using this to help level a parking lot and the contractors just love it - it probably saved us $500 in materials we didn't have to purchase for filling in and leveling the parking lot. I used it to set the slope on a flat roof and again it probably saved us $200 in materials. This is a fine quality item.

I’ve used the $600 Dewalt laser for years and it’s a good level. I’ve also been a Klein guy for 25+ years, but never purchased anything other than hand tools from them. I was skeptical, but figured half the cost of the Dewalt was worth a shot. I was pleasantly surprised that not only was it worth the $250 I paid, I’d easily pay $350 for it (of which it may be in the near future….LGB). Incredibly bright and precise green laser inside and out. Seems to be built just as robustly as the Dewalt I’m well accustomed and the controls are very similar and easy to use. The ability to plug it in via USB device without the use of a battery is also incredibly helpful. So far I am more than pleased with the Klein Laser Level. Hopefully it’ll hold up just as long as it’s competition. Im sure it will. Edit: Been about a year, still works great and original battery still kickin!

Basically the perfect laser

Works great! I had never used a laser so I wasn’t sure I could trust the line at first but after checking the first few with a level, I can say it is very accurate. Has definitely made my life easier on many projects! Great value in my opinion.

Why did you pick this product vs others?: Great item! Good bang for the buck! I used a few lasers ( Bosch, Milwaukee, dewalt) but I kept coming back to this Klein one in particular 93PLL 1 beacsue it has a caring case 2 because it has a rechargeable battery and 3 its a Klein product jk I was just happy with it don’t go with the lower model one which is 93CPLG you’ll regret it in comparison spend the extra bucks quality is great feature are great and the value is great. Try it you won’t be disappointed. Also got the tripod waiting in that.

TL;DR: This device _will_ charge via a USB-C cable, but it's not smart enough to tell modern chargers that it only supports DCP, and many modern chargers will not attempt it on their own. USB-C is just a connector, not a protocol, and the thousands of protocol combinations it can carry are absurdly complicated. There are dozens of different power specifications that USB-C can carry with mixes of ignored, accepted, suggested, and required implementations even within the mostly common mature BC1.2 standard. Power sources, cables, and receiving devices can implement a dizzying mixture of these implementations. It is non-trivial to understand what that trio of factors actually supports, and in what ways they're attempted. The issue with Klein Tools 93PLL's charging is that it _only_ supports a rather simple implementation of DCP which does not take any effort to signal back to the charger its limited capability, and most cheap USB-C chargers do not try. (technically its a bit more complicated than that, but explaining it accurately isn't going to help anyone reading a product review.) This results in the undesirable behavior of many modern chargers not providing power to the device from a USB-C connector. A well designed PD charger will eventually attempt a "dumb" DCP test (D+ <200Ω D-) after it fails to establish PD and BC1.2 handshaks, but this behavior is not yet common. A DCP _only_ charger, e.g. a dumb "wall wart" with USB-C connector, will always charge just fine. Some "charge only" USB-C cables implement the DCP short as part of their natural wiring (the super cheap ones,) and a few of the best charging cable models even verify and apply the DCP short for you in the cable after PD and the rest of BC1.2 fail. Please find attached photos demonstrating the above in simple setups. Note: - In the photo with the device charging from a basic PD charger (anker PowerPort III) with an inline analyzer, that the analyzer is injecting the PD handshake back to the charger to turn it on. - The "charge only" 100W multi-connector spool cable is enabling power to the device from a basic PD charger due to its own inbuilt capabilities making up for the source and destination not figuring it out themselves. - The upturned "wall wart" 3A USB-C charger demonstrates the device's basic DCP ability. - The analyzer inline between the 3A DCP charger and device does _not_ have any PD or other protocol injection, demonstrating the D short, >1A supply, and lack of any protocol. As with pretty much every other headache USB-C has brought upon us, it's rather hard to assign blame here. All devices are functioning within the byzantine specifications required. Should Klein have paid the extra $3 per unit (even more back in 2021) for a better BC1.2 or PD chip? Possibly, but most other devices with a USB-C charge-only port don't either. Should basic "smart" chargers try to implement the entirety of the USB charging specs? Probably, and maybe one day they will, but most do not. Should we as consumers demand better interoperability of USB-C connected devices? Maybe, but how many people are going to actually understand the problem and effect change in such a fast commodity market? Should technologists demand reasonable to understand and commonly implementable standards? Absolutely, but the USB-IF has made it painfully clear that just ain't gonna happen, and its only getting worse. A significant deciding factor in my purchase of this device is its battery. I haven't disassembled the 29026 Li-Ion battery pack yet, but from its dimensions and specifications I feel safe to assume they're just 18650 or some similar cell. Much easier to replace when the time comes than sourcing whatever weird pack i'd discover after completely disassembling some other unit. As for a review of the rest of the device, i've only had it for a day, and it appears to function as advertised. Beams are sharp and reasonably bright for the laser class/price. Dead zones from the reflector housing pillars are not too large.

Nice laser for the price. Battery is very good and the magnet is very strong.

High quality laser. Easy to see inside and easy to setup.

Muy nítido el haz de luz verde, excelente compra
