Batteries & Charging

Everything that stores or moves electricity, from a $4.49 charging cable to a 12kW hybrid solar inverter. Three very different jobs live here: charging your phone, replacing a dead battery, and running a system off-grid.

Charge your phone and devices

• 120W 20000mAh Power Bank ($14.99) - the big one. Enough capacity for several full phone charges and fast enough to top up a laptop.
• Magnetic Wireless Power Bank ($11.77) - snaps to the back of the phone, no cable to carry.
• 5-in-1 Charging Dock with Alarm Clock ($31.99) - clears the nightstand of four separate chargers.
• 360° Rotating Magnetic Cable ($4.49) - the cheapest upgrade here, and the one that stops connector wear.

Replacement batteries

• 12V 7Ah Lithium Motorcycle Battery (YT14AH-BS) ($99.99) - pre-charged, maintenance-free, 1500+ cycles with built-in BMS. Lighter and longer-lived than the lead-acid battery it replaces.
• 5000mAh Power Recliner Battery Pack ($129.99) - up to 824 recline cycles with an LED indicator, fits most power reclining furniture.

Solar & off-grid power

• MPPT Solar Charge Controller 20A ($69.99) - 12V/24V auto-adaptive with 98% efficiency, works with lead-acid and lithium banks. The right controller for RV, van and cabin setups.
• 3000W 12V Vehicle Inverter ($29.99) - runs mains appliances from a vehicle battery.
• KE-F 10kW/12kW Hybrid Solar Inverter ($1,299) - UL certified US version for whole-home off-grid and backup power.

How to choose

• Power bank: watts, not just mAh - 20000mAh tells you how much, 120W tells you how fast. Both matter, and only the second one saves you time.
• Match the battery code exactly - a motorcycle battery must match the size and terminal layout, so check the YT14AH-BS reference against your current battery.
• MPPT beats PWM - an MPPT controller extracts noticeably more energy from the same panels, which is why it costs more.
• Size the inverter to the load - add up the wattage of what you want to run, then leave headroom for startup surge on motors and compressors.

FAQ

What size power bank do I need? 10000mAh covers a day out, 20000mAh covers a weekend or shared charging. Check airline limits before you fly.

Is a lithium motorcycle battery worth it over lead-acid? Yes for weight, lifespan and maintenance. It's pre-charged, sealed and rated for 1500+ cycles.

Can I run a house on the hybrid inverter? The 10kW/12kW KE-F is built for off-grid and backup use and is UL certified for the US. Installation should be done by a qualified electrician.

Will the MPPT controller work with lithium batteries? Yes, it supports both lead-acid and lithium, with 12V/24V auto detection.

How fast is delivery? Items marked US stock ship in about 3-5 days with free shipping to most US regions.
