GIGA Pump - Portable Air Pump for Inflatables, Mini Air Pump Inflator USB Rechargeable, Waterproof DC Pump for Air Floats Mattress Balloon Swimming Rings Kid Toys Inflation-Deflation, 4 Nozzles

Dropped out of packaging and the "top" popped off. However works just fine and has inflated 2 large sleeping pads x 3 trips without recharging. For larger inflatable items like air mattresses would probably need recharging every trip. Noisy, but the time it saves, plus the compact size, is worth it.Design improvement suggestions:- hand strap or gear clip as this is small and easily buried in camping gear- Make 18650 battery removeable so customers can upgrade for better battery life.- More durable case, the top removed from mine after one drop and had to be glued back. Still works fine.

This is a nice air pump that performs as advertised. My only complaint is that the charging port cover is not a very flexible material; so mine snapped in half the first time I connected the charger. It's not meant to be waterproof, so I'm not too concerned, but it seems like they could have used a less brittle rubber, like silicone. Overall, it's good enough, though.

I looked at every air pump on Amazon, with a need to pump up a large raft at the beach and an air mattress at home. This device is small for convenient transport in a beach bag, but powerful for quick inflation, and the battery, being lithium-ion, lasts a long time. I haven't been able to exhaust it yet, and I don't have to worry about it degrading like other technologies. There are a lot of cheap knock-offs out there, but this one is the real deal. Only negatives are that it is somewhat noisy, although every air pump I've ever used is at least as noisy if not louder. Also, the adapters it ships with are limited in size, although they work OK for my needs. It's not a great fit for the air mattress (which is a Coleman brand) but I had another adapter that made it work. These sort of air pumps are designed for high capacity, not high pressure. That means it will inflate fast, but will not create the firmest result, so you may need to finish off by mouth or with a high-pressure pump if you need something extremely firm, like a Stand-up Paddleboard. I did not receive any compensation for this review - this is an unbiased perspective. If you're wondering if this is worth the extra money, it is.

I used this on a camping trip and it was very handy in quickly filling several camping mats. The most important thing was it helped with getting a fire started. I did a cold camp with temps in the low 20's. Most of the wood was frozen and as it thawed it became difficult to burn. Without this item we would not have been able to keep a fire burning. Occasional burst from this pump foced enough air to get the heat going. Any item that serves multiple uses on a trip is well worth taking. It is lightweight and easy to use. I give this item 2 thumbs up and I highly recommend it. The batteries were strong enough to fill 3 camping mats and use on our fire several times throughout the night. It still had plenty of charge when I got home. The motor is very strong and performed better than an air pump I have that ran on 4 C batteries. It sounds like a mini hairdryer and could be used for such if needed. Great product.

LOVE THIS PUMP! Im a big backpacker, and I have a super high loft sleeping pad ( for any experiences backpackers out there; I have bad hips, dont judge ;) ) that takes FOREVER to blow up by mouth. I had a "thermarest "backpacking pump before, and it literally took 15 minutes to blow up. This pump took less that 2 minutes! No kidding! after mine, the entire rest of my camp mates used it too! This little guy is powerful and didnt rum out of juice for at least 2 trips without being charged (I didnt want to risk it after that)! It weighs double what my old pump did, but Its well worth the extra ounces. The attachments fit my sleeping pad and came with several more. Great little gadget!

The device functionality is excellent, but unfortunately the valve adapters are too small for the inflatable mattress I use. Wrapping my fingers around it to form a better seal works somewhat, but I'm still unable to get a very full inflation, even when topping up with the mouth valve + needle adapter. I'll probably need to custom make something to get the seal tighter. Otherwise, this is a great and very portable inflator you can use for car camping and travel, and would probably be excellent for inflating pool toys, small camping pads and things like that.

Does not work very well at all. Used it on two different air mattress brands and the pump shuts off before filling the mattress. Its not even a firmness issue, it won't even completely start the inflation process, leaving at least half the mattress still flat and the sides pressed together and shutting down on its own. I bought this to have a compact air inflation tool so as not to have moisture from my breath cause issues with the inside of the mattress when camping.Garbage, does not work.The rubber cover for the MicroUSB charge port broke off the first time I opened it to charge the unit.The only thing that does seem to work correctly is the large adapter seems to work well with the Klymit Insulated Hammock V mattress. Like a previous reviewer stated, its the only type of inflation port that the unit seems to have the correct adapter for.

I’m using it with my ALEKO inflatable boat. It has a perfect fit to the inflation ports on my ALEKO and fills very fast. You still have to finish inflation with the boats manual pump as there is no final pressure control on this product, but it’s perfect for the majority of the work. Universal USB charging makes it easy to transport and water resistant covers allows one to bring it on the boat and keep it ready when needed.
