Effective November 10, 2026
Amp Hour Supply (amphoursupply.com) is a California business (“we”, “us”). By placing an order you agree to these terms, our shipping and returns pages, and our privacy policy.
Orders and prices
- Prices are in US dollars. Shipping is added at checkout and shown before you pay.
- Your order is accepted when we send the shipping email, not when you pay. Until then we may cancel it, for example if the warehouse runs out, the price was clearly wrong, or the order looks like fraud. If we cancel, we refund the full amount to your card.
- We may hold an order for a quick check before it ships. If we can’t confirm it within 24 hours, we cancel and refund it.
- Warehouse counts on the site update every few hours, so now and then an item runs out after you’ve paid. If an item can’t ship within 7 days of your order, we cancel that item, refund it and email you.
- Special-order items are final sale. The product page says when an item is a special order.
Sales tax
We charge sales tax where the law requires it, based on the delivery address. Today that’s California. If we start collecting in another state, you’ll see it at checkout before you pay.
Using the products
- Read the maker’s manual before you install anything. 12V and 120V systems can start fires or hurt people if they’re wired, fused or loaded wrong.
- Our guides, calculators and product notes are general information to help you plan. They aren’t a design for your boat, van or RV. If you aren’t sure, use a qualified marine or RV electrician, and follow ABYC, NEC and local rules where they apply.
- We don’t install anything and we don’t inspect your system.
California Proposition 65
California’s Proposition 65 requires a warning on products that can expose people to chemicals the state lists as causing cancer or reproductive harm. Where a maker or our distributor supplies one, we show it on the product page above the Add to cart button. Learn more at www.P65Warnings.ca.gov.
Limits on what we owe you
To the extent the law allows:
- Product warranties come from the makers. We don’t add a warranty of our own, but we’ll help you make a claim.
- If something goes wrong with an order, the most we owe is what you paid for that order.
- We aren’t responsible for indirect losses, such as a missed trip, a lost catch, or damage from a product installed or used against the maker’s instructions.
Nothing here takes away consumer rights that can’t be waived.
Resale and marketplaces
Our prices are for end users. We may cancel orders that look like resale on marketplaces, because some brands don’t allow it.
The site
Text, guides, calculators and our own drawings belong to us. Product names and logos belong to their makers. Please don’t copy our pages wholesale.
Disputes
California law applies. If something’s wrong, email us first at [email protected] and we’ll try to fix it. Any court case goes to the courts of Santa Cruz County, California, unless your local consumer law says otherwise.
Changes
We may update these terms. The version in force on the day you ordered applies to that order.
