pure sine or modified?

Asked by rosco June 19, 2020

Modified sine. Seems unable to charge a laptop through the power supply. I have used the Ridgid brand before but they don't last. Also note that the 140 Watts is peak not running.

Does this produce a pure sine wave or modified sine wave? Thanks,

Very dirty power
Going to return ours immediately. The power from the 110 outlet is so dirty, our electronics were going crazy plugged into this. Maybe this would be good for a FAN or something simple that doesn't require clean power. Really disappointed. I thought DeWalt was a quality product.

Response from DeWalt 12 VoltMay 11, 2021
Thanks for your feedback. This is a relatively common issue. Usually if you restart the unit a few times, it will eventually pick up charging.
