Amazon, swap out AA batteries in compatible devices, and eliminate battery changes — particularly for items that remain stationary like holiday lights, strip lights, and similar products. You could cut costs with a solution like this, even when factoring in the low prices of Costco’s budget-friendly Kirkland batteries and Amazon Basics’ similarly low-cost alternatives.
Here’s how Lenink’s adapter and batteries function: The system provides a constant power supply to the battery-operated device through an ultra-slim and flat cable linking to a core dummy battery. When the three AA batteries are placed into the device and the power adapter is connected to an outlet, the adapter delivers power as long as it remains plugged in. Since these dummy batteries are actually components of the adapter and not rechargeable batteries, there’s no need to recharge or replace them.
These batteries and the power adapter are designed for devices that need low electrical current — the system delivers 4.5 volts and 1 A. Therefore, they cannot power devices that consume high amounts of electricity, but they work excellently for accessories such as holiday decorations, strip lights, clocks, and other low-power gadgets.
