JOWAY 115W 150,000mAh Power Bank

JOWAY 115W 150,000mAh Power Bank — This appears to be a high-capacity portable power bank marketed under the JOWAY name (or as a generic unit using the brand). Note that official JOWAY models typically max out well below this capacity, so this is likely a third-party or rebranded high-capacity unit with marketing-oriented ratings.

Important Notes on Capacity & Performance

• Real usable capacity is almost always significantly lower than the advertised mAh figure on ultra-high-capacity banks (often 50–70% of the claimed number after conversion losses and voltage differences).
• A true 150,000 mAh bank at typical lithium-ion voltages would be very large and heavy (several kilograms) and may exceed airline carry-on limits (usually restricted to ≤100 Wh / ≈27,000 mAh at 3.7 V).
• 115 W total output is high enough to charge many laptops and multiple phones simultaneously, assuming proper PD/QC protocols are supported.

Pros: Extremely high claimed capacity for multi-day or multi-device use; high wattage for faster charging of phones, tablets, and some laptops.

Cons: Capacity claims are frequently inflated; bulk and weight; potential safety/quality concerns with unbranded ultra-high-capacity units; may not meet airline regulations.
