With more than double the capacity of a standard recliner pack, this 5000mAh lithium-ion battery supports up to 824 recline cycles per charge, even carrying an 85 kg load, so a power recliner, sofa, or lift chair can go longer between charges. An LED screen reports the remaining charge at a glance, and the universal 2-pin connector matches the plug used on most electric recliner mechanisms for a tool-free swap. The included US-plug 110V adapter brings it to a full charge in under 5 hours, and the pack is rated to handle charging up to 131°F and discharging up to 140°F, with reliable performance across a -14°F to 104°F range for year-round use. At 7.68 x 3.15 x 2.17 in and 2.71 lbs, it's still compact and light enough to install or move without help, and its tangle-free design keeps the 47.24 in cable tucked away so there's no loose cord underfoot, a real plus in a household with kids, pets, or older adults moving around the furniture.
