Order Confirmation

As soon as you place your order, you will receive an order confirmation e-mail.  This means that we have received your order in our system and your payment method is pre-authorized for the purchase.

Then, we automatically reach out to our suppliers to confirm that it is in stock and available for immediate shipment.  If your item is on backorder or unavailable, we will void the pre-authorization and reach out to you via e-mail.  If your item(s) are available for immediate shipment (within 2 business days), we will process the charges and submit the order for shipment.

Hassle-Free Returns & Exchanges


We strive for a stress-free, hassle-free return process.

In order for the process to take place as smoothly as possible, we ask all customers to observe the following requirements.

  1. We have a 30-day return policy, which means customers have 30 days after the date the item shipped to request a return. Unfortunately, we are unable to accept returns beyond 30 days after the item shipped.
  2. Most items are easily returned within 30 days of the shipment date. To initiate a return, please contact us at If the return is accepted, we will send the customer a return shipping label as well as instructions on how and where to send the package. Items sent back to us without first requesting a return will not be accepted.
  3. To be eligible for a return, the item must be in the same condition as it was received and in its original packaging.
  4. We may ask for confirmation of certain details as to why an item is being returned for verification or if a warranty request is involved.
  5. The customer is responsible for return shipping costs. We do not charge restocking fees.
  6. To assure your refund please use a trackable mail service. We are not responsible for lost or missing packages.


Upon the receipt of the return package, the item will be examined and a full refund will be issued to the original method of payment. A refund receipt will be emailed to the email address provided during the original purchase.

Refunds are processed as soon as the refund request is approved - that means that the money leaves our account immediately. If a refund has not yet been received, first check the bank account again. Then contact the payment method company as it may take some time before the refund is officially posted. We have seen some credit card companies take up to 30 days to show that the refund has been put back on the card. 


The fastest way to exchange an item is to order it separately when the return is accepted.  Depending on inventory availability, we may be able to initiate a direct order of the exchange product after the original item is returned.


Cancellations are accepted up to the point of shipment. If the order has shipped, the customer is responsible for return shipping charges. Refunds are only issued to the original purchase method.


The customer must inspect the packaging on arrival.  If damage is present, the customer should make note of it when signing for delivery. If the item arrives damaged, the customer must send photos to and we will process an insurance or warranty claim on the customer's behalf.

The Wagan Tech¬†SlimLine 1250 Watt Inverter is high output, compact, and slim; hence the reason it is in¬†their¬†Slimline family of power inverters.¬†They¬†dubbed this line ‚ÄúSlimline‚ÄĚ as all of the inverters are high performance but as slim and compact as possible.

Taking a cue from its big brothers, the SlimLine Plus 1250 Power Inverter is small in size, but packs a punch. With 1250 watts of TrueRated power, 3 AC receptacles (wall outlet style) like you'd find in your home, USB power port, thermal cooling fans, and a host of built-in protections, the SlimLine Plus 1250 Power Inverter is exactly what you have been looking for.

In your vehicle, boat, motorcycle, RV, truck, RV, motorhome, campground, kids soccer games or anywhere you need to convert DC (battery) power to AC (household) power is where the SlimLine inverter will shine! 1250 Watts Continuous means you can run your appliance without worry; unlike lesser inverters. Blender, TV, game systems, refrigerator, microwave, computer, kitchen appliances, CPAP, and other home electronics can be powered!

TrueRated Power

TrueRated Power is Wagan Tech’s coined term for truth in advertising and performance. Simply put, our TrueRated inverters are tested at full load (the number printed on the inverter) and will sustain that load continuously for 24 hours.

For example, our SlimLine 500 Watt Inverter will run for 24 hours straight with a 500 Watt load. Our competitors claim "continuous wattage" when in fact most are only rated at 20 minutes of continuous wattage. After 20 minutes, the competitors output wattage will drop down by as much as 25% of their claimed wattage (in a 500 watt inverter, that can be a 125 watt loss!).
