Shell SH924 Jump Starter Review

My wife and I have 3 old AGM emergency battery jumpers between us.  They are big and heavy and we basically never have one in our vehicle when we need one. They just sit in our utility room and we occasionally will use them if our cars are dead in the driveway.

The Shell Jump Starter and Portable Power Bank (sh924) has made them all obsolete.

The reason is simple; better product in a more manageable size with extra functions and great safety features.

The old AGM starter batteries basically go bad if they sit around too long, they are too bulky and heavy to easily keep in a vehicle, and they kind of suck.

The shell battery, although not perfect (I explain in a bit) is by far superior.

Size

First is the size;  This emergency car starter is small.  It is light.  It has a handle that makes it easy to carry or position.  There is also a strong battery in the base that lets you position the jump start and it stays where you want it.  And there is a multi-function light.

So let’s go through it.  If your emergency starter is so bulky you don’t want it in your car you are not going to have it when you need it.  The Shell battery jump started uses lightweight high power lithium ion batteries so it is small.  The battery itself is probably only 3x5x7 inches.  It is a little bigger than that though because it has a nice emergency light and battery clamps built-in.  Overall the size is small enough that any car would have room for it, it is basically the size of a set of jumper cables.

The white light works great under the hood when you are connecting it to your battery when using it.  There is also a built-in red flashing light.  This is perfect to put out at night if you are ever stuck changing a flat on the side of the road.  Drivers these days are distracted, I want something that will catch their eye and keep me or my wife safe on the roadside.

There is also reverse polarity protection so you don’t short the battery that you are Jumping. There is high temperature cutoff if the battery gets too hot.   There is also reverse charge protection, low battery protection and short circuit protection.

Extended Battery Life

The Shell battery has a whooping 88.8 Wh of battery life.  The battery is small enough that you can use it anywhere to help charge up your electric device of choice.  The 88.8 Wh is basically enough to charge my phone from dead to full at least 4 times.  I was able to do small booster charges without registering any loss of battery capacity on the 4 light battery status LED.

The two minor complaints I have on this unit are 1) there is no place on the unit to store the 110 volt ac charger.  If you don’t have this and the battery is low on capacity you are out of luck.  2) the AC charging is slow.  In my world this is not a big deal, you just leave the SP924 plugged-in over night and there you have it.

Shell SH924 Jump Starter Pros & Cons

Pros:

• Portable and easy to store
• Extended battery life
• Multiple safety features included

Cons:

• Slow AC charging speed
• No storage for 110V AC charger

Overall Impression

With most emergency battery banks like this you will want to charge them after each use.  Starting a car takes a lot of umph.  The Shell Jump Starter can work with gasoline or diesel 12 volt cars up to 11 and 8 liters respectively, that is a big engine!

So, it’s time to get an emergency starter that you will actually have when you need it.  It’s small enough to put under a seat and you will never get left standing in the rain trying to flag down a jump again. That’s what you get with the Shell SH924 Jump Starter ($169.99).
