None of the supplied nozzles with Max Pump jammed nicely into a Boston valve
My Max Pump packed after less than a year and about 20 uses. Replaced with bulkier Max Pump Plus
Only replaces air-bagging; still need to top up by mouth and/or hand pump
Will discharge eventually, unlike manual methods, and will eventually die for good

What they say
My name is Max Pump 2020. I can quickly inflate and deflate your swimming tube. air mattress. and other inflatables. With vacuum bags .I can create more capacity for your suitcase and wardrobe at home. When in outdoor.I can provide oxygen for your burning ovens. enabling you to enjoy your food more easily.

Review
An electric pump to save a couple of minutes’ packraft air-bagging? Do me a favour! That’s what I think when applied to bulkier IKs where a two-way barrel pump is fast and easy. But factor in cost, weight, size, USB rechargeability plus supplementary uses and, for a packraft, FlextailGear’s range of pumps (above) is worth a punt.
Air-bagging is a clever idea to inflate a typical packraft, but on some days it’s not the most intuitive of actions, perched on seaweed covered boulders. Once a day is fine, but on a trip where you’re airing up and down a few times a day, the effortlessness of the Max Pump is welcome. A good case to point was my paddle on the Wye where accessing my Rebel 2K’s internal storage pockets to get to the camping gear each night meant re-inflating the boat every morning. The Flex pump would have made this less tiresome. Another example is getting back from a tiring sea paddle and wanting to reinflate the boat to rinse and dry properly. Plug in the Flexy and get on with other after-paddle chores.

Max Pump adapters but none fitted a Boston valve’s two ports just right
Actually the grey rubber nozzle (right) will push and seal into the main threaded port, and with my second Max Pump Plus, there was a hard plastic nozzle to fit a Boston’s mushroom valve (middle) too.
But to reduce loose bits, I made a 2:1 adapter (left) to fit both ports, using tape to make a good seal.

Out of the box
With Max Pump I got the pump, four nozzles, a short USB-A lead and a small bag. While one nozzle loosely fitted a Boston valve’s threaded airbag port / dump valve, nothing fitted the one-way valve body. You’d think with Boston valves so common on Chinese-made slackrafts, packrafts and cheaper IKs, this Chinese brand would include a Boston valve nozzle. Luckily, I’ve amassed loads of adaptors and nozzles, and one 16mm (5/8″) adaptor fitted the pump’s main nozzle and jammed into the Boston port. [The orange Max Pump Plus included a nozzle for the valved port].

Off a computer allow two hours to fully charge the pump out of the box. After just three fills (12 mins?), it took just hour or less to get the green light. Off the mains is faster.

I estimate the volume of my Rebel 2K was 240 litres, (12 jerricans) so at the claimed flow rate of 300 L/min (currently the highest in Flextailgear’s range of mini pumps), that ought to take less than a minute. In fact it took 2:30s to reach the equivalent of airbag pressure (full volume; above).
But this was pushing through the one-way valve, (like a car tyre) not direct into the hull via the airbag port / dump valve which has no resistance.
Now with a bigger TXL with a volume of around 350 litres, I inflate directly through the screw port into the hull: 2:20s and if you’re quick you don’t lose much air screwing the cap on. Then I Flex for another 30s via the valve (or do 20 breaths to save the battery) and finish off with the handpump.
According to the Flextailgear table above, my heavier orange Max Pump Plus has 10% less power and max pressure than the Max Pump, but it’s hard to verify any of this data other than weight. The fact is, either pump does a packraft in a couple of minutes.

My comfy full-length Exped Synmat XP 9LW – which also needs air-bagging to avoid humid breath – inflates in just 25s. And as many will know, air-bagging a sleeping mat in a cramped tent when you’re worn out is not one of the joys of camping.
The Max 2020’s 3600mAH lithium battery is claimed to run for 40 minutes, so that ought to do at least 10-15 raft fills plus a few mats, when camping. I imagine the Max Plus will be the same.

Deflating either of these items is of course as easy as rolling them up, but getting the last bit of air out can be tricky, even though it can save a lot of packed volume. Pump suction definitely works on my Seawave IK because the one-way valve can be pulled open with the bayonet nozzle. On the packraft and mat, you have to suck from the unvalved airbag port, and by the time you’ve plugged that, some air gets drawn back in. I find just rolling up, squeezing, then sucking the last of the air by mouth works best, as your hands are free to get to the valve cap fast.

Max Pump Plus will do my Anfibio TXL in under 3 mins

Last word to Sven from Anfibio: “Can’t live without one anymore. Cannot remember when I last used an inflation bag.”
These young people, honestly.

Packyaking in Whitianga (NZ)

At a Dive shop in Whitianga on the North Island’s Coromandel peninsula half a day from Auckland, I asked the teenage girl left at the till which way the tidal currents flowed around here. She smiled at me like I was an idiot and explained slowly.
‘Well, when the tide comes in it like, comes towards you, and when it goes out, it sort of goes away.’
Before I got into sea paddling that’s what I would have said, but I explained what I meant, that tidal flows moved to and fro in a given direction along a coast, not just in out, in out, like a Can-Can dancer’s legs At any constriction or headland it’s a good thing to know when planning or timing a paddle. She looked it up on the internet.

‘Anticlockwise.’

‘Thanks.’

Tides apart, did I really think the surging expanse of the Pacific would be calm enough for a humble 10km coastal packayak round the cliffs of Cook Bluff to the famous and much fridge-magneted tourist icon of Cathedral Cove (painting below)? No, but now on my wavelength, Dive Girl went on to offer me tomorrow’s gloomy forecast: 4-metre swells, 35 knot gusts and occasional showers of razor-billed flying fish.
A good day for a cliff walk then. Coming back next evening from Cooks Beach, I  was a little appalled to see Mercury Bay awash with white-capped rollers, as if some tsunami was on the go. Surf’s up, if you have the nerve.
It was right here in 1769 that Captain Cook and his crew – on the hunt for the fabled Terra Australis – first raised the British flag on the New Zealand shore while engaged in observing the transit of Mercury.

Maybe I’d get a chance the day after, my last. But even in the calm morning, the storm’s after-swell was still pounding the cliffs and beaches of Mercury Bay. Who knows how it was at the Cove of Broken Dreams which, they said, was still closed from the land side, anyway.
Luckily, the cliff-rimmed natural harbour of Whitianga was sheltered from all this Pacific aggression. And better still, the tides were ideally timed to be swept into the inlet, before getting spat out on the mid-afternoon ebb like a retching gannet’s breakfast.

Settling up on a grassy strand near the marina, I realised I’d left my pfd at the hostel – this after noting a warning sign advising that all in <6-m long boats required them. Oh well, if spotted hopefully the harbour master will zoom up alongside me on his jet ski and lend me one for the day. As it was, I was heading inland where there’d be no one.
Once tempered up via my hose extension, I scooted over the yacht-clogged harbour mouth, ferrying across the strong current filling the shallow inlet, tilting marker buoys as it went. I was told later that, partly as a result of dredging a channel for marina access, that Whitianga’s natural harbour was fastest flowing in New Zealand.

On the west side, under a wave-carved overhang (left) I hopped out to temper the MRS again. I like an inflatable as firm as possible but am finding, perhaps due to its larger than normal volume for a non-pump inflatable, that the S1 commonly needs a second pump up a few minutes in.
I’m now wondering if something about half the size or volume of my 600-g K-Pump Mini would be handy to get the Nomad up to operating pressure in one go. This eBay pump (right) cost me just 3 quid posted and is actually similar to the mini pump Alpacka initially offered with their $2000 Alpackalypse. With a pump like this, after high-volume air-bagging, you could judiciously pump to a highish pressure on the shore – assuming the cheapo eBay pump can hack it. Yes, a pump’s another thing to carry/lose and the comparatively bulky K-Pump will do the job in a few short strokes. But unlike a paddle, it’s not ‘mission critical’, as they say in the movies.

Fitting a PRV and being able to pump away until the PRV purged (as I do with my Seawave IK) would be even easier, because you could also happily leave the boat out on a hot beach without fear of it exploding into a thousand ribbons of ruptured TPU. PRVs are unknown on packrafts so maybe I’m over-thinking it, but double-tempering is a bit of a faff even if, as humans go, I have a good pair of nicotine-free lungs.

Anyway, I padded southwards, weaving among the lifeless yachts and cruisers, reminding me of our Hayling Island paddle last summer. Let me tell you, in this world there are a lot of massively under-used boats bobbing around and gathering algae.
Once past a sinister big black tug, the bay opened out and I was in the clear. Nearby, alongside a jetty below a cliff leading to a dwelling hidden in the bush, I spotted this pioneering-era carving.

Beyond here the shore looked oddly mangrovey and inaccessible. Mangroves this far south at nearly 37°? I’d only ever seen then around Darwin where I’d once eaten a so-called oolie worm which feeds in their trunks. Sure enough, turns out hereabouts is the southermost extent of mangroves.
I’m not so keen on this sort of drab coastline, but live and let alternative lifeforms live, I suppose. In fact it was fun to probe the passages below the shady groves as it was due to reach 30°C today.

It took a bit more idle nosing about before I finally located the channel leading southeast to the two small rivers which fed the harbour inlet. The channel narrowed as the supposedly slack tide swept me into the tangled maze of salt-loving woodland. Curving left and right, south and east, as the scaly boughs closed in, it occurred to me that this far down in the bay wouldn’t be a great place to get lost and then stranded in thigh-deep, oolie-ridden silt for the next few hours. Who knows how quick the tide turns. Anticipating this, I’d clocked a hilltop landmark over on the western hills to help orientate myself, then pushed on in as far as I dared, getting maybe 500m from shore before spinning around into the still-rising tide and scuttling back out into the open.

The tide really ought to have turned by now, carrying me back the way I’d come, but the forecast nor’westerly was on time and in my face. Luckily the Nomad’s generous stub nose stopped me making a mockery of the harbour’s 5-knot limit so it was a long hour’s slog back to the harbour mouth, bent against the breeze and slapping waves. A similarly windy afternoon on the Wairoa River a few days back must have got me into paddling shape, so the effort was all put down to good exercise.
Once past the marina, I’d hoped to slip below the jetty, under the harbour master’s cabin and out into Mercury Bay itself. Maybe cruise below Shakespeare Cliffs and then land on Buffalo Beach, like a proper Pacific navigator. But it was not to be. Chances are I’d have just embarrassed myself, tumbling through the surf and into the shore fishermen’s barbed hooks.

My time was up in NZ. Next day, rolling my cleverly adapted UDB (more below) to the bus stop, all was as calm as a kiwi’s cozy nest. I was reminded how sea kayakers must feel when they haul all the way up to the Summer Isles to be met by tent-bothering gales, only to find great conditions as they pack up.
It’ll be there next time and for sure the east side of the Coromandel looks like the fantastic place for some fabulous sea paddling. The beachside hostel I stayed at laid on hefty old SoTs for free and there were plenty of kayak touring outfits in town and around. Give it a go if you ever find yourself down here.

For this trip moving from airport to airport and in a bid to spare my creaking back, I mated my trusty Watershed UDB to a chopped-down lightweight folding trolley I’ve used on previous packboating trips. With chunky zip ties and a strap, the shortened frame fitted securely to the rugged UDB’s back harness tabs.
My load was way under the airline limit, but the thinking was that, once packboating my planned river for a few days, the UDB and small trolley would still be compact, compared to a regular wheeled travel bag.
It was all a way of stopping myself buying the painfully pricey but actually only 500g heavier Ortlieb Duffle RS 140 I’ve been eyeing up. Fitted with an IP67 TiZip (not as good as the UDB’s brass drysuit zip), it’s the biggest one they do, so ought to take my Seawave IK and gear. Lacking a backbone frame of Ort’s RG duffles,
the 140 actually rolls up even smaller (right) than my DIY contraption.
A handy side benefit (which might also apply to the airtight Ortlieb), was that being able to inflate my UDB into a rigid airtight sausage made it easier to wheel around (but not as comfy as a full-framed wheel bag). I got some odd looks giving my bag a blow job by the arrivals luggage carousel, because at departure check-in I had to tug the zip open a bit to ensure it would air-off safely at 32,000 feet.
In my hand I carried my nifty Ortlieb 30-L Travel Zip.
