When you need to start your engine because you have flat batteries, you don’t want to worry whether the device you have will work or not. High-quality Stanley jump starters are made to do the job and more. The best Stanley jump starter can start your engine whatever the state of charge of your batteries. Most have an emergency air compressor you can use to fill your tires with air when they are down in pressure or flat.

Stanley jump starters are not exactly all the same. They vary depending on the charge they can deliver. The bigger the charge and the more accessories, the more expensive will be the jump starter. It is best to choose the jump starter that suits your requirements.

When you get your Stanley jump starter, you will need to give it an initial charge using the mains. Once charged, you can leave the jump starter in your vehicle or at home. If you need to use it in an emergency, you just have to attach the jump starter to your battery terminals like you would with the leads from someone else’s well-charged battery and press a switch. Your engine should roar into life. If it doesn’t, there is something else wrong with your engine, not a flat battery!

How long to recharge a battery after jump-starting an engine?

Note that all jump starters only get an engine started when your batteries are flat. They don’t recharge your batteries. As long as your alternator is working correctly and the battery isn’t dead, you should be able to recharge your vehicle battery after running the engine for 2 to 3 hours. Just give your engine a good run.

If your alternator is faulty, you will soon know about it, because your flat battery won’t recharge. Check the fan belt and electrical connections before calling a mechanic or tow truck.

Of course, it all depends on why your batteries were flat in the first place. The best jump starter cannot be a substitute for weak batteries or badly functioning alternators, but is an emergency lifeline.

Final thoughts

The Stanley jump starters are useful emergency devices as long as you have the room in your vehicle to stow them. They can all jump start an engine if the batteries are flat, but won’t fix any other problems with your electrical supply. If your alternator is not charging properly or your batteries are on their last legs, it may be better to get a new alternator and batteries rather than relying on a jump starter.

All of the Stanley jump starters here have a useful LED swiveling light if you get caught out at night and some sort of charging potential for small electronic devices.

Most but not all of the Stanley jump starters have an additional air compressor that can be used to keep the pressure up in your tires or pump up an airbed or bicycle tires. Some reviewers have complained about the reserve charging status of their jump starters. They do need to be recharged regularly and more often if they are at the smaller end of the range
