Great investment. All the people I delt with at Hampshire Generators were very knowledgeable and offered good advice and help. Love the equipment the powerbank meets my needs and is relatively light and easy to use around the home and the solar panels work well even in low sun... am tempted to invest in another battery pack and possibly the solar tracker... my use is powering devices around the house, mitigating enery bills and providing a range boost for my EV. Thank you Hampshire Generators. - the entire experience was a rewarding and fun journey.
