Alternatives

• USB power bank— Pocket-size for phones and small devices; no AC or high-draw output.
• Deep-cycle battery + inverter— The DIY version — cheaper per watt-hour, heavier, needs assembly.
• Generator— More sustained watts, plus noise, fuel, and exhaust.

Maintenance notes

• Top up every few months in storage; LiFePO4 chemistry is happiest stored around 50–80%.
• Recharge promptly after each outing so the next one starts full.

Buying considerations

• Size by watt-hours against your real loads — a 100W ham rig transmitting draws far more than it receives.
• LiFePO4 chemistry gives 3–6× the cycle life of older lithium-ion packs.
• Regulated 12V DC output matters for radios that brown out as voltage sags.
