The fear of the blackout is spreading. It would be good to have at least some power in reserve! This fear leads to a boom in power boxes - large mobile batteries with mobile connections. While they used to be popular with craftsmen and outdoor fans, many now want a box like this – preferably with a solar panel for charging.

That fits the current offer from Jackery. Along with a 200-watt foldable solar panel, the brand's flagship Explorer 2000 Pro is being sold on Amazon at a discount of €580, or 20 percent. The price of 2899 euros then drops to 2319 euros. The box stores about 2000 kWh and like all devices in this class, it is just as portable. At almost 20 kilograms, however, the box is not for hiking or cycling holidays. Nevertheless, with the dimensions 38.4 - 26.9 - 30.8, it is more compact and also noticeably lighter than comparable boxes. You can find the detailed test here.

A box in the 2000 watt class can feed almost any device that has a plug. If you disregard power-guzzling tools and a full-fledged stove with oven. Coffee machines, water heaters, induction hotplates and not to forget a hair dryer, which also has some power, are possible. The box uses Li-ion technology for this. At its peak, the box delivers 4400 watts at 230 volts. The box has two 230-volt sockets, a 12-volt car outlet and USB ports – including a USB-C outlet with 100 watts (Power Delivery). The box is reserved when it comes to the number of connections, but it is also smaller. It is charged with an enclosed power cable and two inputs for solar. They are in a jack format that is typical for Jackery – but panels from other suppliers can also be connected using the appropriate adapter. You can find the detailed test here.

The bundle includes a 200-watt jackety solar panel - SolarSaga 200. A total of six such panels can be connected to one box, and the bundle includes one. However, six panels require a lot of space both when setting up and transporting. In the protective cover, a module measures 54.1 - 61.5 - 4.1 centimeters. When unfolded, the panels are over two meters long.

Thanks to the discount, the panel is now (almost) free with the box. The box can also be used as a balcony power station without a blackout - all you need is an extension cable into which the consumers are plugged.

The discount is only granted for the bundle with one panel, there is no discount for the other combinations. To do this, the coupon must be activated. The 580 euros will be charged at the checkout. You may not press the "Buy It Now" button. The offer runs until Monday 10.10 or "while stocks last".
