TSA & FAA Air-Travel Approved (90 Wh)

At 90Wh (25,000mAh @ 3.6V nominal), this battery is well below the strict 100Wh TSA carry-on limit. Permitted in carry-on luggage across all international and US commercial flights without airline pre-approval.

Cell Rated Capacity	25,000 mAh (90.0 Wh)
Nominal Pack Voltage	3.6 V Li-ion (5S / High-rate)
Total Maximum Output	200 W Multi-port
Typical Laptop+Phone Recharges	~2.5 Full Cycles
Estimated Efficiency Factor	85% - 90% (PD Buck-Boost)

Active Charge Profile Summary

Total output load of 182W distributed across 3 active ports with an estimated runtime of 29 minutes under full load, or ~2.5 charges for a typical laptop+phone combo, fully TSA compliant (<100Wh).

UGREEN Nexode 200W Deal Analysis: Why Power Distribution Matters

The UGREEN Nexode 200W (25,000mAh) portable power bank frequently hits deal roundups because of its rare USB Power Delivery 3.1 Extended Power Range (EPR) support. Unlike generic 100W power banks, its primary USB-C port negotiates 28V at 5A to drive 140W fast-charging to a 16-inch MacBook Pro or gaming workstation while simultaneously maintaining 60W+ to a second laptop or high-draw handheld like the Steam Deck.

Flight Legal Boundaries: Aviation authorities enforce a rigid 100-watt-hour ceiling for lithium-ion batteries in carry-on bags. Many high-capacity banks push 27,650mAh (99.5Wh) which risks manual airline inspection or scrutiny at international security checkpoints. By engineering the Nexode 200W at exactly 90Wh (25,000mAh @ 3.6V nominal), UGREEN maintains an unambiguous 10Wh safety buffer below the TSA threshold.

Nominal energy, capped load and runtime rounding

Your browser does not support video.

Read the explanation

The saved calculator stores ninety watt-hours and estimates minutes by dividing that energy by selected load, multiplying by sixty and rounding downward. Default port requests sum to one hundred eighty-two watts, giving twenty-nine minutes. The travel-named preset selects thirty and twenty-seven watts with the third port disabled, totaling fifty-seven and giving ninety-four minutes. Bars compare these rounded source estimates at five pixels per minute. They are arithmetic from stored nominal energy, not measured battery endurance or a guarantee of USB performance. The preset name does not establish airline eligibility, safe charging or verified device compatibility. The first port allows one hundred forty watts, the second one hundred and the third twenty-two point five. Their maximum requests total two hundred sixty-two point five. The function caps only its totalWatts field at two hundred before estimating runtime, producing twenty-seven minutes from ninety watt-hours. It does not redistribute individual requests or model negotiation. Bars compare requested and capped reported total at two pixels per watt. This distinction matters when reading the exported per-port breakdown: individual values can sum above its total field. No hardware power limit or delivery measurement is proved by these UI calculations. The office preset activates three ports at sixty-five, thirty and ten watts, totaling one hundred five and yielding fifty-one whole minutes. The solo preset requests one hundred forty on the first port only and yields thirty-eight. Bars compare the estimated minutes at five pixels per minute. A source comment mentions ninety-seven-percent efficiency, but the actual runtime expression does not multiply by efficiency. We preserve that code behavior rather than present its estimates as measured usable capacity.
