lipo rider pro alternative to provide up to to 2A current

Hi guys, actually I need to implement a system that uses a lipo battery, and a can be charged using a solar panel. the lipo rider pro is a good option, however, it can only provide up to 1A, and I am using a GSM shield that needs 2A during peak time.

what are other alternatives for the lipo rider pro that can allow me to charge the lipo battery with a solar panel and provide a constant 5V - 2A ?
