Ordered these as have quite a few items in the house that need high capacity batteries (such as an outdoor weather station and digital camera) and normal Ni-Mh batteries don't sometimes cut the mustard. The item arrived well packaged in a strong small card box with instructions and a USB-C charging cable . The box doubles as a solid storage box and charger and holds 4x AA Lithium batteries. These have a much better power/drain curve that normal batteries and are ideal for devices with intense power needs or long term use.
Charging takes around 3hrs for a full charge and the batteries are ready to go. The cells themselves are well made and there are no concerns around potential leakage etc. Price break is excellent, with the cells being rated for approx 1200 charge cycles. Great piece of kit- will be looking for additional cells and seeing if they do a AAA version. Highly recommended.
