TOPGREENER’s official Amazon storefront is now offering a selection of its wall outlets on sale from $22 with free shipping for Prime members or in orders over $25. Our favorite is the 6-pack of 3.6A Dual USB/15A AC Wall Outlets for $48.01 shipped. Down from its normal going rate of $60, today’s deal saves up to 20% and marks the second-best price that we’ve tracked in the past 12 months. These plugs replace your existing wall outlets and offer dual 15A AC plugs as well as two USB-A ports capable of a combined 3.6A output. This means you’ll be able to charge USB devices without having to plug any adapters in. Head below for additional TOPGREENER deals.
