Why we recommend it
The Jaswill is the cheapest way to get the Addalock idea; choose it when price wins, the AceMining when you want a more compact modern version, and the DoorJammer when your door has no usable strike plate.

Why it is our Best Value
Budget travelers, college students in dorms and shared apartments, and anyone who wants a door lock in every bag without spending much are who the Jaswill portable door lock is for. It appeals to people who have read about portable door locks and want to try one before committing to a pricier brand, or who simply need a spare for a second traveler.
It earns the Best Value slot because it makes the whole category an impulse purchase. The editors we draw on noted exactly that: it brings portable door security under $10. The design follows the proven strike-plate formula, with a metal insert that hooks into the frame and a sliding lock body that holds the door closed from inside, so you give up little in function compared with the original. It comes in a small pouch and weighs almost nothing.
On the road the Jaswill portable door lock goes on the hotel door at night and comes off in the morning without tools or marks. In a hostel private room or an Airbnb, it adds the resistance a flimsy latch lacks. Students use it on dorm doors, and parents often buy two so each kid traveling abroad has one. Because it is cheap, it is also the lock you leave in the travel kit permanently instead of moving it between bags.
The drawback mirrors the Addalock's: it only works on inward-opening doors with a standard strike plate and enough gap, and fit and finish are not as refined, so it can feel looser on some frames. As with every add-on device, confirm you can remove it in a second. Skip it if you want the most polished version; choose it if you want the cheapest working lock.

Frequently asked questions
Straight answers to what travelers ask most about jaswill portable door lock.
Is the Jaswill portable door lock as strong as the Addalock?
It uses the same strike-plate principle and resists the same kind of forced entry, so in practice they behave similarly on compatible doors. The Addalock has a longer track record and tighter finish. Both are deterrents for a door you cannot fully control, not vault-grade security.
Will it fit a hotel door with an electronic key card lock?
That depends on whether the door frame has a standard strike plate with a gap for the metal insert. Many do; some tight electronic frames do not. If the insert will not seat without forcing, do not use it. Check the Amazon listing for current compatibility details.
Can I take it through airport security?
It is a small metal travel accessory and normally passes through security in a carry-on without comment. Packing it in your carry-on is wise anyway, so it is available on the first night even if checked luggage is delayed.
