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
