The set of batteries is composed of lithium iron phosphate batteries and lithium cobalt oxide batteries. The 12 V output circuit outputting a current in the range of 100 A to 400 A is directly connected to the set of batteries without interference with the charge-discharge protection circuit. The charger is convenient for carrying, and is capable of providing power for different electrical instruments including for an automobile."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Portable backup charger","description":"A portable backup charger includes a set of batteries; a charging circuit; a charge-discharge protection circuit; multiple DC-DC voltage adjusting circuits including a DC-DC 19 V-output boost circuit,","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9643506","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
