Well techincally the only thing you are risking is your macbook charger. This thing interfaces with the Wall and your brick. If anything fails it can potentially screw your macbook charger. My guess is this is essentially a 60W or more lithium battery charger, if this uses lithium battery, and a cheapo 60W square wave inverter on the other end.

Given that this supposedly supply you with 3-4 hours of battery, here are my calculation on the internal battery capacity:

macbook pro 13 has 71Wh battery
This gives around 10-12 hours of battery life fully charged.
worst case:1/4*71Wh = 17.75Wh.

If these are lithium batteries, then you are looking at 4.8Ah assuming 3.7V nominal.

So not much IMO. I guess this is why they are so poorly rated.
