FLEXTAIL Pump Review: Zero Pump 2 vs Tiny Pump 3X
This FLEXTAIL pump review compares two small electric pumps that take the effort out of setting up and packing away your sleeping mat. The Zero Pump 2 keeps things slim and simple, while the Tiny Pump 3X adds a proper tent light and higher rated airflow. We'd choose the Zero for a stripped-back kit; the 3X if a pump and lantern in one sounds more useful.

Figures are published specifications, not a timed head-to-head test. Zero Pump 2's quoted 28 g excludes its battery, so it is not a ready-to-use kit weight.
What changes with Zero Pump 2?
The Zero's appeal is easy to understand: a narrow pump that slips into a small corner of the pack, without carrying lighting you might already have. The version we stock is Zero Pump 2 with the 900 CHT battery, not the original Zero Pump. Its output rises from the original's 180 L/min and 2.5 kPa to 200 L/min and 3.5 kPa.
The removable battery is a useful distinction. You can carry a compatible spare rather than wait for the pump to recharge, although charging means taking the battery out first. Operation stays straightforward: double-click to start, single-click to stop. Six nozzles give you options, but take the one your mat actually needs rather than carrying the whole set.
Does the 3X's lantern make a difference?
Yes—if you would otherwise pack a separate tent lantern. The 3X hangs overhead and starts with a gentle 15-lumen setting, useful for settling down without flooding a small tent with light. There are brighter settings up to 400 lumens, though maximum brightness is more than most small tents need.
Separate pump and light buttons keep the functions distinct. Both sit flush, so finding them by touch takes practice; the charging port gives your fingers a useful reference point. Charging directly through the body is less fiddly than removing a battery.
What matters more than the headline output?
The nozzle fit. The 3X completed the pillow and mat inflations faster in the original-Zero comparison, but neither pump's adapters gave a perfect fit on the Big Agnes mat used. Check your exact valve before a trip: a broad set of adapters is not a promise of universal compatibility.
Packing down. Deflation can be as useful as inflation, especially when you're trying to roll a mat inside a small tent. Move the nozzle to the suction port and open the mat's valve appropriately. Keep the airflow path clear; internal material can obstruct suction as the mat flattens. Follow the mat maker's instructions and don't force an incompatible valve.
Noise and firmness. Neither is silent. Inflate before neighbouring campers settle down, and keep a manual option for late arrivals. Depending on your mat and preferred firmness, a final top-up may still be needed.
Which would we choose?
Choose Zero Pump 2 if you already have your lighting sorted and want a slim pump with a replaceable battery. It keeps the useful inflation-and-deflation functions without adding a lantern.
Choose Tiny Pump 3X if you want one small item to inflate your mat, help pack it away and light the tent. For that mix of camp jobs, it's our more versatile pick.
