How to Know the Fake Capacity of Multi Function Jump Starter

Recently, the multi function jump starter is super popular during these years. AGA , as the inventor of multi function jump starter , has a responsibility to give some product information for the consumers to know more about the product!

Today, I would like to tell you a fake capacity problem in current jump starters. So that you will not be cheated!
Let's do it now!

First of all, I will let you know, there are 2 kinds of lithium battery jump starter in the market. One is Li-PO battery, another is LiFe battery. Most of the multi function of jump starter we see in the market is Li-PO.

The standard voltage of Li-PO is 3.7V, the standard voltage of Li-PO is 3.2V.

For a example:
Multi function jump starter
Capacity: 12000mAh ( true capacity)
Input: 12V/1A

The 12000mAh of Li-PO jump starter is : 1.2 Ah*3.7V=44.4Wh.

Full charging time is: 44.4Wh/12V*1A > 3.7h.

You know the power will lose when charging, not 100% power transfer's rate.
Let's See the Fake Capacity One


This is a jump starter I found online.The capacity of this jump starter is 68800mAh mentioned-above.

So 68800mAh ( 68.80Ah*3.7V=254.56Wh) is 354.56Wh,if the 68800mAh capacity is true.

So the full charging time should be over 21.2 hours. (254.56Wh/12V*1A>21.21h)

But according to the description of full charging time is just 3-4 hours. Then you will know, this is a very serious fake capacity!!

Hope it will be helpful for you to know more about the jump starter. Any problems or questions, just contact with us directly.

First-Look Review of the AGA PB79200 Lithium Portable Power Station

We love our electronics, and we’re not ashamed to admit it. While humans once survived without smart phones, GPS, streaming media, and the Internet, we’ve adapted to the digital conveniences of our lives, and frankly, these days it’s hard to imagine life without them. While we study new products, analyze features, and even argue over which brands we like best, one need remains constant across all devices: electricity. Now that may sound obvious, but when you stop to think about it, most of us take access to electricity for granted. The closest most of us get to experiencing no electricity is being stuck somewhere with a dying phone battery and no charger. Stop and consider for a moment what would actually happen without power. The inconvenience of losing access to your social media feed would soon be eclipsed by the realization that you had no lights at night and your food was warming up in your refrigerator. With the general reliability of our infrastructure, losing power for a...
