do not buy

my car had 4 tires about 26psi. I filled them up to 32. It took forever, and the battery was half gone. I noticed in the specifications they do not list the amp/hour of the battery. Additionally the plastic shell is very thin. Cheaply made.

Using the compressor on 4 tires will decrease the battery level of the unit. It is recommended to charge the unit after every use.

the original from many years ago worked well, but the handle was spring loaded on the side and could be cumbersome, the next one had no handle but corner holes to pick it up with, the air hose on the last one was a pai. to re- pack i to the trap door, plus it has like the original an ac plug to attach a power cord to, this new one has correct the handle issue and the repacking of hose issue, plus even though people prefered the ac plug it had before, that caused the issue of not being able to charge it while on the road, so the new ac dc adapter that they use now was as I think a correction fpr that issue. so my opinion is this is the best version yet. am very pleased with it. right out of the box it jumped my fprd deisel truck and tooped off my cars tire, one reviewer said no place to store the ac dc adapter, wrong, it fits where the tire hose is. you're welcome

The charger should not be separate, attach it!

Why would they not attach the charger permanently to the unit? Or a compartment to store it. They want you to lose it... I expected better. Charge 5 more dollars and make a quality product.

We have an earlier version of this Stanley jump start / Compressor / USB power unit and have loved using it. We purchased this new one and have been very disappointed. It can be used much the same, but instead of recharging in 4-6 hours it takes 40. instead of pluging into the wall it has a tiny 9 volt external charger which gets so hot while charging you dont want to touch it. I will not wait for nearly 2 days to be able to use it after the battery is used up and the high temperature does not seem safe. We are returning it and will try to find another brand designed like our earlier Stanley.

The charger included with this unit is not a 9 volt charger. You may be using the wrong charging adapter. If replacement accessories are required. Please contact Baccus Global Technical Support at 877.571.2391 or email at CustomerService@Baccusllc.com
