It holds the charging for a long time. I have an old car in my garage which needs to start with a jump starter if I haven't used it for a few weeks. I used this jump starter on that and it works great. Before this, I was using the 10,000mAh jump starter which I bought from Costco that was also working fine. It is very easy to use and it is a compact size easy to carry this in my car. It is durable and has great value for money.
