How to change the battery for my 4345 coleman lanterne
There are two adapters for that lantern; one for the house and one for 12volt. You simply connect one of the adapters and it will power the lamp and also charge it. Those two adapters came with the lamp; if you don't have them you can contact Coleman to purchase replacements.

Is it possible to repair my Cobra 1500w to 3000w peak power inverter?
As the Cobra 1500w inverter is constructed analogous to a high-frequency "switching" power supply, it is not recommended to modify it to exceed original specifications. For any inverter intended for applications exceeding 2000W transient peak, it is highly recommended to use a low-frequency "true-sine" inverter. Your Cobra inverter is designed for low-deman applications, and is insufficient for high-demand applications.

2000 watt inverter blows 60 amp fuse under load
I have a background in electronics so i hope i can help. Now after reading this i have the feeling this item does not put out 2000 watts cause if that were the case it should draw somewhere near 147amps. This is because to find out amps you need to take the 2000 watts and divide it by 13.6 volts (assuming what the vehicle runs at) that gives you amps. watts/volts=amps.
