User questions & answers

Question:	Can you take it to an airplane
Answer:	Dear Customer, sorry, it can't work with other inverters on the same grid, it can't be stackble, hope your kind understanding, thanks.
Question:	the usb c, how many amps at 20v
Answer:	This is 120V inverter
Question:	Can it be used with a Dell Inspiron laptop
Answer:	I think this depends on the electrical design of your boat or RV. My yacht has an automatic transfer box handling shore power and generator power or switching to this inverter.
Question:	How does it manage pass through charging when only 45 watts can go in and at least 60 watts go out? What happens when the battery dies
Answer:	You would need to contact Xantrex to find out. Lithium ion batteries have a different charge control system and charge profile. This Xantrex product is set up for Pb Acid flooded or absorbed electrolyte battery charging. I don't believe it can handle Lithium Ion. They may have a separate product for lithium ion. Contact them

User questions & answers

Question:	why wont it charge? Plugged everything in. Nothing
Answer:	Please use a 30W PD 3.0 charger to charge the portable power outlet.
Question:	Will this work for devices requiring a 3 prong outlet? Specifically a dell inspirion and a chrome book
Answer:	Yes, it works for devices requiring a 3 prong outlet.
Question:	Air mattress compatible
Answer:	It depends on the type of pump that you have for your air mattress. I have seen AC powered mattress pups, the kind that would normally plug into a standard wall outlet, and DC powered pumps, the kind that you'd plug into a 12v outlet in a car. This battery pack will run an AC pump, with the outlet on the top, as long as it's not a 3-prong outlet. (I've never seen an air mattress pump that has a 3-prong plug on it.) If you have a pump that normally plugs into the 12v (cigarette lighter) plug in a car, then no, this will not connect to it. I hope this helps!
Question:	Will this charge a Microsoft Surface Pro
Answer:	Yes, but I can’t charge to full level.
