The American Airlines flight smoke incident in Dallas rippled through every airport in the country within hours, but San Francisco travelers had a distinct advantage: two stores that already stocked exactly what the new battery-safety rules require. While other cities scrambled to find TSA-compliant gear at airport markups, locals could walk into Sports Basement's Presidio location or drive across the bay to REI Berkeley and leave with fire-resistant battery cases, properly rated adapters, and the kind of backup gear that turns an airline emergency into a manageable inconvenience. The stores occupy historic buildings—an Army commissary and an ice rink—but their inventory reflects current TSA guidelines updated within 48 hours of the Dallas incident.

Why recent airline incidents changed how we pack
The American Airlines flight smoke incident in Dallas this month—traced to a lithium battery in checked luggage—reminded every frequent flier that what you pack matters as much as where you're going. Airlines tightened enforcement immediately. Battery packs over 100 watt-hours now trigger gate checks at SFO and OAK. Portable chargers without visible capacity markings get confiscated. The FAA updated its guidance within 48 hours, and TSA officers at Bay Area airports report they're pulling twice as many bags for secondary screening.
San Francisco travelers responded by clearing shelves of TSA-compliant battery cases and fire-resistant organizers. Sports Basement's Presidio location saw a 300 percent spike in travel-gear sales the week after the Dallas incident. REI Berkeley sold out of their Pacsafe anti-theft bags twice in August. The run isn't about panic—it's about smart travelers realizing that airline safety rules exist for actual reasons, and the gear to comply with them costs less than a single checked-bag fee.
Both stores stock what you actually need, not airport-kiosk markups on generic adapters. The Presidio shop occupies the old Army commissary building at 610 Old Mason Street, open Monday through Friday 10am to 8pm, weekends 9am to 7pm. REI Berkeley sits in the refurbished Iceland ice rink at 2727 Milvia Street—yes, the scoreboard and roof sign are still there—with hours running 11am to 8pm weekdays, 10am to 7pm weekends. Curbside pickup at REI runs until 5pm daily if you're racing the clock.
Sports Basement Presidio: military-grade organization meets civilian travel
The Presidio store feels like it never fully shed its commissary past, which works in travelers' favor. The layout forces you past the travel section near the old 'Bakery' sign, where staff arrange battery cases by watt-hour capacity rather than brand. Every case displays a printed TSA reference card. The selection runs from basic neoprene sleeves ($12) to hard-shell Pelican-style cases with foam cutouts ($89) that protect not just your power bank but also camera batteries, vape devices, and the tangle of international adapters you'll actually use.
General Manager Shelley Berniker's team stocks Anker, RAVPower, and Mophie battery packs that clearly print their capacity on the casing—the detail that keeps you out of the TSA secondary line. They also carry lesser-known brands like Zendure, whose 100Wh packs squeeze maximum capacity within the limit and include a carabiner loop for clipping to a backpack strap during security. Prices run $40 to $95 depending on capacity and port count.
The real find sits in the back corner where luggage meets outdoor gear: fire-resistant document pouches designed for wilderness permits but perfect for passports, backup credit cards, and those irreplaceable paper tickets some international carriers still issue. LokSak makes a fireproof version for $18 that weighs two ounces and fits inside any carry-on's laptop sleeve. After Dallas, these became the quiet bestseller nobody talks about but everyone who travels monthly quietly adds to their cart.
REI Berkeley: the Iceland rink's second life as adapter central
Walking into REI Berkeley means stepping onto what was once ice, though the chill remains—dress accordingly even in August. The travel section occupies the former penalty box area, which General Manager Tom Purcell's team turned into a testing station. Every international adapter on the wall plugs into a live outlet board showing which countries each model actually works in. The display updates monthly based on customer returns and travel reports. It's saved countless travelers from discovering their 'universal' adapter doesn't cover the UK or won't handle a hair dryer's wattage in Japan.
REI's house-brand Co-op travel gear undercuts name brands by 20 to 40 percent while meeting the same specs. Their $24 USB-C travel adapter includes a 30W power delivery port that charges laptops, not just phones. The $45 packing cube set uses recycled ripstop with compression zippers that actually reduce volume rather than just organizing it. For travelers who pack camera gear, REI stocks Peak Design's Tech Pouch ($50), which includes elastic loops sized exactly for battery cases, cable wraps, and SD card holders—no more dumping everything loose into your personal item.
The bike shop at the front of the store does quick repairs on luggage wheels and retractable handles, which most travelers don't realize until their roller bag dies the morning of a flight. Labor runs $15 to $35, parts extra, but the work happens while you browse. They keep common replacement wheels in stock for Samsonite, Travelpro, and Away bags. The turnaround beats shipping your bag to the manufacturer and hoping it returns before your next trip.
What the Dallas incident actually means for your packing list
Lithium batteries belong in carry-on bags, period. The Dallas fire started in a checked bag's main compartment where nobody could reach it until the plane landed. Current rules allow batteries up to 100 watt-hours in carry-ons without airline approval; 101 to 160 watt-hours require approval; anything over 160 stays home. Most phone battery packs run 20 to 30 watt-hours. Laptop batteries hit 50 to 80. Camera batteries rarely exceed 20. The problem comes from unlabeled batteries or damaged cells that short-circuit.
Both stores sell battery testers ($15-$25) that check remaining capacity and flag cells developing internal shorts. Nitecore's four-bay charger ($32 at REI Berkeley) includes a test function that reads each battery's voltage and capacity, then displays whether it's safe to fly with. This matters more for photographers and drone operators carrying six or eight spare batteries than for casual travelers with one phone charger, but the Dallas incident proved that one bad battery in someone else's checked bag affects everyone on the plane.
Fire-resistant bags don't prevent fires—they contain them long enough for crew to respond. LiPo safety bags, originally designed for RC hobbyists, now show up in travel sections at both stores. These fiberglass pouches ($12-$35 depending on size) seal with Velcro and can handle a battery fire for 15 to 20 minutes, enough time to fill a plane's lavatory sink and submerge the bag. Flight attendants train for this scenario now. The bags weigh almost nothing and fold flat when empty, so there's no reason not to carry one if you're traveling with multiple battery packs or anything using 18650 cells.
The gear that actually travels well versus what looks good online
Airport stores sell the same universal adapters everyone buys and half the people return because the prongs don't lock firmly into European outlets or the whole unit blocks the second socket. Sports Basement and REI both stock Ceptics, whose adapters use a twist-lock mechanism that holds tight and whose slim profile leaves adjacent outlets free. The five-piece international set costs $28 at Sports Basement versus $45 at SFO's Hudson News for a single flimsy adapter.
Compression packing cubes sound gimmicky until you actually use them on a two-week trip. Eagle Creek's Specter compression set ($65 at REI) reduces packed volume by about 30 percent compared to regular packing cubes, which means the difference between checking a bag or carrying on. The fabric shows wear faster than non-compression cubes, but they last three to four years of monthly travel. Sports Basement carries a similar set from Shacke for $35 that sacrifices the water-resistant coating but compresses just as effectively.
The best travel purchase most people skip: a secondary phone charger that stays packed. Anker's Nano 20W charger ($16 at either store) weighs less than an ounce and folds flat. Keep it in your travel bag's interior pocket so you never pack your everyday charger the morning of a flight and realize at the gate that your phone's at 12 percent. This costs the same as airport parking for 90 minutes but prevents genuine trip-disrupting panic.
Practical notes
Sports Basement Presidio at 610 Old Mason Street opens at 10am weekdays, 9am weekends, staying open until 8pm Monday through Friday and 7pm on weekends. Street parking along Old Mason fills by 11am on Saturdays; the Presidio's free lot behind the building rarely fills. REI Berkeley at 2727 Milvia Street keeps similar weekend hours (10am-7pm) but opens later weekdays at 11am, closing at 8pm. Their curbside pickup runs until 5pm daily—order online, park in the marked spots on Milvia, and staff bring your order out in under five minutes. Both stores accept returns on unused travel gear within 90 days, though opened battery packs and adapters are final sale for safety reasons. The PresidiGo shuttle stops at the Presidio store's corner every 30 minutes; AC Transit's 51B line stops two blocks from REI Berkeley.
