Ztylus Stinger Car Emergency Escape Tool, Spring-Loaded Window Breaker, Car Safety Hammer, Seatbelt Cutter and Window Glass Breaker, USB Car Charger, 2 USB Ports Max 2.4A (Black)

So far I have not been disappointed buying this phone charger/seatbelt cutter. The size is great for traveling and the blade is sharp enough to cut through thick seatbelt material. Shattering glass with it takes getting the hang of it but works great once you get use to it. It's great for gifts or to keep in multiple vehicles in case of emergencies.

This works well in my 2014 car, the two USB ports are both still working after several years. I use the ports to charge both lightening and usb-c devices. Highly recommended. I have not used the window breaker tool or the knife/seat belt cutter component.

Well, thank goodness I haven’t had to use it, but it’s just nice knowing I have one in each car

Biggest concern I saw in reviews was possible loose fit in the lighter socket and chance of flying loose in an accident. i have no such issue with an older Subaru, a Lexus or a newer Honda, and the fit is firm. Only minor issue is that the blocky, right-angled top may be obstructed for some cars: For example, Lexus lighter socked is recessed (under a panel when not in use), and using this device requires removing the ash tray (which is fine for me, since I never use the ash tray). The advantage of lighter/USB models is that you'll just leave it plugged in and have no reason for it to be out of reach in case of emergency, Possible disadvantage is that if you have anything plugged in to the USB ports at that moment, there's still a chance that the Stinger could get pulled out of the lighter socket -- weird things happen during accidents, right? Oh well. Package comes with test sheet for the spring-loaded window punch (put that target on a piece of scrap wood to test). I tested the blade with a bit of backpack webbing. All good. USB ports work fine (not fast charge, normal voltage). Competitive price. No battery nor flashlight (generally doubles the price).

I had several emergency tools before but they all end up getting lost somewhere. I found this tool and initially I thought it was just a car charger that cuts seat belt, then I found out it actually breaks windows in case of emergency! Cool beans! I ordered one just to see the quality (and it's great by the way) so now I'm going to order more for my husband and in-laws, and my brother. This is a great product and I seriously think it's gonna save people's life because it is actually always within reach in emergency situations. *Thumbs up for the designer*

I've carried a different version of this tool in my vehicles for years. The problem had always been if you need something like this you're going to need to have it in your hand very quickly. And despite trying to keep it in one specific place, it always ended up being covered by other things ... and being a tool you (hopefully) never need, it's location just isn't something that was always burned into my brain. The fact that this version of the tool sits in one of the cigarette lighters alone is what sold me. It's not buried in the console, door pocket or glove box, or on the floor because the velcro tape trick didn't work LOL. It's just sitting right there in front me all the time ready to go if needed. I saw some reviews that claimed the 2 charging ports aren't really rapid charging. That actually seems to be true ... my iPhone does seem to charge slower using this tool. But that's irrelevant to me. If I need to charge more quickly I have another cigarette lighter and another charger for that. As far as the comments on loose fit, it seems to have the same fit as any other car charger I've used.

My grandchild's car seat was expired and I upgraded to a booster seat. I have arthritis and couldn't get the back tether loose from the hook. I used this to slice the tether (similar material to seatbelt) it cut it effortlessly. I played with the glass breaker on a piece of garbage glass and it broke without a problem.

I saw this device on YouTube channel and thought it was pretty cool. It sounds great to have two extra charging ports and a life saving glass breaker in case of my car dropping into some water crisis. However, there is a problem with the stinger. The mini razor that comes with it is not sharp. I was trying to cut a piece of cardboard out of curiosity this morning. It got stuck in the first few millimeters. That's really disappointing. Imagine a situation I have to cut my seatbelt and this razor can not perform at all. I haven't tried shattering any glass with the spring loaded stinger yet. However I did try it on an aluminum bottle cap. It punched a hole in all right. Just in case, I am going to try to break a glass Mason jar later to make sure it truly has enough power. Other than the razor problem , the stinger and the charger works fine. I do like the charger because it charges pretty fast at roughly 1% per minute. It depends on the phone you have. I have the OnePlus 5t so maybe thsts why it is faster.
