Jump start power bank rosak after 4 years. Used 2 times. Will you buy another one or stick with cables?

My 70mai jump start powerbank is showing signs of ageing and deterioration.

1. The rubber over moulding has gone bad. Just sticky all over
2. Battery already started showing signs of swelling
3. Charges only up to 75% (Still can jump start though)

Given all the signs, its getting riskier to use this. I should just send it for recycling.

Will I buy a new one to replace it? Probably not. 

Bottomline:

Its a nice to have, in order for the backup to work, you must remember to charge it.
As with all powerbanks, they have a lifespan, when start to see the unit swell, time to replace it.
If you are ok with the cost (~RM200++), definitely should get one.

At the end of the day, having the traditional cable would also just work anytime.
