A procurement lead we met at a trade show told us the story we hear about once a month. He ordered thirty 120 kW DC units from the cheapest quote. The quote said four weeks to ship. It shipped in eleven. The CE certificate on the datasheet covered a different power class than the units he bought. When three of the chargers failed within a week, the support was a WhatsApp number that had gone quiet the day the deposit cleared.

The lesson was not that cheap chargers are bad. It was that he had bought a charger, when he should have been buying a supplier.

You are not buying a charger

A DC charger is a metal cabinet with a power module inside. Two suppliers can ship cabinets that look identical on a spec sheet and behave completely differently in the field. What you are actually buying is a factory, a folder of certificates, and a supplier’s willingness to answer hard questions in writing before the deposit, not after.

Price is the last question to ask, because price is the number the supplier controls least once the project is live. A charger that shows up late, under-spec, or unsupported costs more than any discount it saved.

That is why the supplier questions come first. A factory you can audit, certificates you can verify, and a lead time you can enforce are worth more than a lower number on a quote. The rest of this piece works through each in turn.

The certificate folder

Every supplier has logos. You need to see the certificate that matches the exact model and power class you are buying, not a company-level logo.

Ask for the CE certificate for your specific power class, and read the standard it references. In the EU, CE means the unit meets the relevant directives and can trade freely across member states. In North America, CE is the wrong answer entirely: that market runs on UL, not CE, and a supplier who waves a CE certificate at a North American buyer is telling you they do not know the market. For the Gulf, Central Asia, Southeast Asia, and most of Africa and South America, CE is the reference that matters, often alongside a local conformity mark.

We hold CE, TÜV SÜD, and SGS at the company level, and we will send you the certificate for the exact unit you are buying, not a logo. If a supplier will not show you the certificate for your power class, treat that as a red flag, not a paperwork detail.

Lead time is a promise. Get it in writing.

A lead time on a quote is a number someone typed. A lead time in a contract, with a delivery clause and a penalty, is a promise.

The question that separates suppliers is not what the lead time says. It is what happens when the lead time drifts. A supplier with their own factory and their own supply chain can tell you the truth and hold to it. A supplier who is an OEM front for someone else’s factory quotes you a number they do not control, because they are reselling someone else’s production schedule.

Standard lead time on our DC range is around 30 days, and we lock price and delivery together when you place the order. In a market where copper and power semiconductors move every month, the lock is worth more than the discount. A floating quote that looks cheap today is a surprise invoice later.

The lock-in trap

The supplier relationship that burns buyers is not the missing certificate or the late shipment. It is the lock-in that only shows up later.

A charger that speaks a closed protocol means the operator cannot switch platforms without swapping hardware. The network, the data, and the billing all sit in the supplier’s cloud. When the supplier raises prices or drops support, the buyer has nowhere to go.

The fix is to insist on an open protocol. OCPP 1.6J is the reference here. It lets the charger talk to any compliant management system, which means the operator owns the network and the data, and can walk away from the supplier without walking away from the hardware. Ask any supplier one question: if I want to change my software platform next year, do I keep my chargers? The answer tells you everything you need to know. Lock-in is expensive because the exit is not a new software contract alone. It is new hardware, a new install, and downtime while you swap. A supplier who profits from that exit has every reason to make sure you never have one.

Factory and after-sales

A charger is not a purchase. It is a ten-year relationship with a piece of hardware that sits outside in the weather.

Look at two things. First, does the supplier make their own hardware, or white-label someone else’s? Owning the factory means the supplier controls the bill of materials, the quality, and the fixes. It also means the person you are negotiating with can walk onto the line and fix a production issue, instead of forwarding your email to a factory in another country.

Second, what happens when a unit faults? A supplier with local service partners and remote diagnostics fixes a charger over the air in minutes. A supplier with neither sends a truck, or worse, sends nothing.

This is where remote diagnostics and over-the-air updates stop being features and become insurance. Most faults do not need a body on site. They need someone who can see the fault, understand it, and push a fix. Our chargers carry this from the first unit, and we run local after-sales in the markets we ship into.

A warranty is only as good as the path to claim it. A two-year warranty on paper means little if claiming it means shipping the unit back across a border. Ask where the warranty is honored, who pays the return, and what the turnaround is. A supplier with local service partners honors a warranty in days. A supplier without them honors it in months, if at all.

The questions to ask any supplier

Before you sign, get written answers to these six.

Ask for the certificate for the exact model and power class, not a company logo. Ask what the lead time is, and what happens to your delivery and your price if it slips. Ask whether the protocol is open, and whether you keep the chargers if you change software platforms. Ask whether they own their factory or OEM. Ask what the warranty covers and how you claim it in your country. Ask for units they have delivered in your region, and for an operator you can call.

A supplier who answers all six without stalling is rare. A supplier who stalls on any one of them is telling you something, and it is usually the thing that will cost you later.

The red flags that show up early

Most bad supplier stories share the same early warnings. The supplier wants the deposit before answering questions. The certificate they send is for a different model. The lead time moves every time you ask. The factory address does not show up on a map, or they will not host a video walkthrough. The reference customer is always too busy to talk.

None of these is proof by itself. Together they form a pattern, and the pattern is usually right. When a supplier resists a question you have a right to ask, the answer they are avoiding is the one that will cost you later.

How we approach it

We started as a factory, not a brand. We manufacture our own DC chargers, and we hold the certificates in our own name. The protocol side stays open on OCPP 1.6J, so our customers keep their data and their exit. We deliver to Georgia, Armenia, Romania, the Czech Republic, and Finland today, and the units are running on real sites you can visit or call.

We would rather you ask us the six questions above than take our word for any of it. A supplier who invites the hard questions is the one you want, and we try to be that supplier. The next piece in this series covers the thermal specs to check before you buy, so the charger that arrives on time also holds its power in the heat.

Write to sales@anarienergy.com and we will send you the certificate folder, the delivery terms, and a reference you can call.
