3 Surprising Limitations (And Solutions)

"My 500-yuan unit couldn''t handle my coffee maker – turns out peak watts matter more than I thought!" – Outdoor Enthusiast Review

• Peak power traps: Many advertise 300W but fail at sustained 200W loads
• Battery chemistry: LiFePO4 batteries last 2× longer than standard Li-ion
• Solar compatibility: Only 60% of units support efficient solar charging

Pro Tip:

Always check continuous wattage (not peak) and cycle life (aim for 1,000+ cycles). EK SOLAR''s EP-300 model, for instance, maintains stable 250W output even at -10°C.
