I bought a portable charger for my iphone 3gs, my battery was getting low so i put this charger in and now my phone wont switch on?

https://www.quora.com/Why-does-my-portable-charger-blink-and-not-charge

What does it mean when your portable charger is blinking blue? The charger senses this battery condition and as part of it's features gives the blinking indication to say cannot charge this battery. ... A steady charge light usually means that the battery is charging and a blinking light shows that it is charged.

Is the replacement battery an original equipment battery? I bought an aftermarket battery for my Samsung and the phone will not recognize the battery even though the specs are identical. Nice trick by Samsung. See if I ever buy another product of theirs again. Anyhow try putting the old battery back in and see if it will function while plugged in. Otherwise head to the phone store.

Did an Apple Store service this Phone?

The battery is probably dead. You can locate a repair service who will replace it for you for under $50, or you could do it yourself, it's not very difficult. You can easily find detailed instructions on the web, and the replacement battery costs about $5 on ebay.I found good instructions here, that will give you an idea of whether you want to undertake the repair yourself.

I think it may be broken.You need buy a new iPhone battery charger.

I had the same problem a few days ago. this could be because the battery is not connected to the cell phone properly (from dropping it or leaving the cell phone in the sun) and may need something, such as tissue paper or ordinary paper to be folded and put on the one side of the battery which is not connected and this will tighten the connection.
hope this helps
